Evo Mortar is the best Evolution in Clash Royale right now — and most "best Evo Mortar deck" lists you'll find are quietly illegal under the current slot rules. If you copy one of those eight-card screenshots into your deck builder, the game won't let you build it.
Quick answer: In the October 2026 Shocktober meta (Season 88), the strongest Evo Mortar deck is a double-Evolution bait build — Evo Mortar + Evo Skeleton Barrel + Cannon Cart + Rascals + Minions + Goblin Gang + Fireball + The Log — which posts win rates in the 64–71% range on ladder tracking across thousands of battles. If you'd rather keep a Hero, the single-Evolution variant swaps Evo Skeleton Barrel for Hero Ice Wizard or Hero Barbarian Barrel. You cannot run two Evolutions and a Hero at the same time — that's the slot trap this guide exists to fix.
This is a reasoning-led breakdown: which cards, why they work after the recent balance passes, how to pilot the deck, and the exact slot math that trips up every stat-dump list. All deck data is pulled from live ladder tracking (late September–October 2026); card behaviour is checked against Supercell's official release notes.
Why Evo Mortar is the top Evolution in October 2026
Mortar is a 4-Elixir siege building that out-ranges the opponent's Crown Tower, forcing them to react on your terms. The Evolution turns it from a fragile win condition into a self-perpetuating problem: instead of firing boulders, the evolved Mortar lobs Goblins that deal the same impact damage and then stick around as a unit, chipping whatever is nearby. So the evolved Mortar hits the tower and generates pressure while your opponent is busy clearing it — and it unlocks with 6 Evolution Shards.
Tier data from the current cycle backs this up. Across roughly 29,000 Ranked battles tracked between late September and early October 2026, Mortar Evolution ranked as the top-tier Evolution by combined win-rate and use-rate — ahead of long-time favourites like Evo Elite Barbarians and Evo Royal Hogs. The appeal is simple: Evo Mortar punishes the slow beatdown and control decks that are still rebuilding after the balance churn, and it does so for a low average Elixir cost.
A few structural facts that matter for October 2026:
- The game is on Season 88 "Shocktober" (started 5 October 2026), with the balance pass landing at the 6 October maintenance. That pass buffed several win conditions while trimming cycle and defensive cards — it was not a nerfs-only patch, despite what some roundups claimed. Confirm the exact final numbers in the official release notes before treating any single value as gospel.
- Hero and Champion abilities are single-use per deployment (the only exception is Boss Bandit) since the 26 August 2026 rework. Any older Evo Mortar guide telling you to "re-use the Hero ability after the cooldown" is out of date.
- Spirits no longer damage Crown Towers on their own and lost HP in the August 2026 patch, which is part of why slot-efficient chip decks like Mortar bait rose — the old cheap chip tools got worse, and Mortar's guaranteed tower damage looks better by comparison.
The slot rule that breaks most Evo Mortar lists
This is the single most important thing in this guide, and it's where competing articles get Clash Royale wrong.
Since the March 2026 update, every deck has exactly three special slots. Supercell's official update post spells it out: "1 Evo Slot, 1 Hero Slot, 1 Wild Slot (can include either a Hero or an Evo)." Breaking that down:
- 1 Evolution slot — Evolutions only.
- 1 Hero slot — Heroes and Champions only.
- 1 Wild slot — accepts either one Evolution or one Hero/Champion, not both.
So the math is fixed. If you want two Evolutions (Evo Mortar + Evo Skeleton Barrel), you put one in the Evo slot and the second in the Wild slot — which means you have no Hero and no Champion in that deck. If you want to keep a Hero (say Hero Ice Wizard), the Hero takes the Hero slot and the Wild slot holds either your single Evolution or the Hero, leaving room for only one Evolution total.
That's why any "best Evo Mortar deck" screenshot showing Evo Mortar + Evo Skeleton Barrel + a Hero is impossible to build today. Live ladder trackers aggregate card forms loosely and will happily show you that combination; the in-game deck builder will not. Below, both decks are legal.
Best Evo Mortar deck #1 — Double-Evolution Mortar bait
Cards: Evo Mortar · Evo Skeleton Barrel · Cannon Cart · Rascals · Minions · Goblin Gang · Fireball · The Log Average Elixir: ~3.5 · Special slots: Evo Mortar (Evo slot) + Evo Skeleton Barrel (Wild slot), no Hero Tracked win rate: 64–71% across several hundred to a few thousand battles on current ladder data.
This is the purest expression of the archetype and the highest-ceiling build. You run two Evolutions and lean entirely on card quality and cycle rather than a Hero ability.
How it wins: Mortar does the chip; everything else is a bait or a swarm. Rascals, Goblin Gang and Minions overload your opponent's small spells, so by the time they've answered two of your threats, their Log/Zap/Arrows aren't up for the Skeleton Barrel or the next Goblin Gang. Evo Skeleton Barrel is your secondary win condition and your spell-bait anchor — if it connects evolved, it dumps a pile of skeletons onto the tower.
Piloting notes:
- Open with Mortar slightly behind the river on the side with your Elixir advantage, not on a cycle. You want it protected, not sniped off a split-lane push.
- Cannon Cart is your defensive backbone against Hog, Ram Rider and mini-tanks — it tanks and deals real damage, then leaves a cannon behind.
- Keep Fireball + The Log for value, not for chip. Fireball the three-unit clumps (Musketeer behind a tank, Witch, Rascals mirror); Log resets the ground swarm.
- Against beatdown, don't race — defend, then counter-push the surviving units behind a fresh Mortar.
Best Evo Mortar deck #2 — Single-Evolution with Hero Ice Wizard
Cards: Evo Mortar · Hero Ice Wizard · Cannon Cart · Rascals · Minions · Goblin Gang · Fireball · Barbarian Barrel Average Elixir: ~3.6 · Special slots: Evo Mortar (Evo slot) + Hero Ice Wizard (Hero slot), Wild slot empty or holding a second win-con form Tracked win rate: ~64–66% across a few thousand battles.
If you've invested Hero Coins into a Hero and don't want a Hero-less deck, this is your build. You drop the second Evolution and gain a reusable defensive value engine instead.
How it wins: Hero Ice Wizard is an outstanding defensive anchor — the base card slows everything in its splash radius, and the Hero form adds a one-time ability on deployment for a swing moment. Because the ability is single-use per deployment now, treat it as a defensive panic button or a lethal finisher, not a spammable tool. The rest of the deck plays identically to Deck #1: bait out small spells, let Mortar chip, counter-push.
Piloting notes:
- Use Hero Ice Wizard behind the Mortar so a successful defense flows straight into offense.
- Barbarian Barrel replaces The Log here for the extra body and a touch more defensive value against first-hit troops.
- This build is more forgiving for mid-ladder players because the Hero gives you a bailout against a push you misread.
Which Evo Mortar deck should you run?
| Factor | Deck #1 (Double-Evo) | Deck #2 (Hero Ice Wizard) |
|---|---|---|
| Skill ceiling | Higher | Moderate |
| Forgiveness on defense | Lower | Higher (Hero bailout) |
| Peak tracked win rate | ~71% | ~66% |
| Needs a Hero unlocked | No | Yes (Arena 5 / 200 Hero Coins) |
| Best for | Ranked grinders, confident cyclers | Mid-ladder, Trophy Road climbers |
If you're pushing Ranked and comfortable cycling fast, Deck #1 is the stronger weapon. If you want a safety net and already own a Hero, Deck #2 loses very little and plays more comfortably on the ladder.
What to avoid with Evo Mortar
- Don't siege-chip into a counter-push deck blindly. Decks built around Ram Rider, Hog or bridge spam will trade your Mortar chip for face damage. Against those, Mortar is a defensive building first.
- Don't fire the Hero ability on cooldown instinct. It's single-use per deployment now. Holding it for the right swing wins games the old habit loses.
- Don't run two Evolutions and expect a Hero too. The slot rules forbid it — pick a lane.
- Don't chase a static "all Evolutions" tier list. Supercell adds and rebalances Evolutions roughly monthly; Evo Mortar's standing is an October 2026 read, not a permanent law.
FAQ
Is Evo Mortar a no-skill deck? No. Mortar is one of the higher-skill win conditions in Clash Royale because placement, timing and spell management all matter — a mis-placed Mortar gets sniped and does nothing. Evo Mortar raises the ceiling (more chip, more spawned pressure) but it doesn't lower the floor; bad placement still loses. It's "easy to feel, hard to master."
Can you run two Evolutions in one deck? Yes, but only two, and only if you give up your Hero slot. You place one Evolution in the dedicated Evolution slot and a second in the Wild slot. That leaves no room for a Hero or Champion. If you want a Hero, you can run only one Evolution. This is a result of the March 2026 slot rework (1 Evo slot, 1 Hero slot, 1 Wild slot).
What's the best Hero for an Evo Mortar deck? Hero Ice Wizard is the strongest pairing in the current meta because its base-card slow is permanent defensive value and the Hero ability gives a single-use swing moment. Hero Barbarian Barrel is a solid budget alternative if you haven't invested Hero Coins elsewhere.
Did the October 2026 balance patch change Mortar? The October balance pass landed with the 6 October Shocktober maintenance and adjusted a mix of cards — it buffed several win conditions while trimming cycle and defensive tools, rather than nerfing everything. Check the official Supercell release notes for the exact per-card numbers before treating any specific value as final; preliminary balance lists change before they go live.
What arena do you need to use Evo Mortar? You need the Evolution slot (unlocked at Arena 3) and a copy of Mortar you've evolved. To run the double-Evolution build you also need the Wild slot, which unlocks at Arena 10. Heroes (for Deck #2) unlock at Arena 5 and cost 200 Hero Coins.
Is Evo Mortar better than Evo Elite Barbarians or Evo Royal Hogs? By combined win-rate and use-rate in the late-September-to-October 2026 tracking window, Mortar Evolution sat at the top of the Evolution tier, ahead of both. That's a current-meta read tied to this patch, not a permanent ranking — it can flip the next balance pass.
