What are the best Clan War decks?

From the decks we counted (1 Sep – 24 Oct 2026, top Path of Legends players), the four that share no card and score best once each win rate is cut by its margin are Lava Miner 56.7% ±3.5 (n 765); Minion Giant Control 58.1% ±5.4 (n 320); Spell Bait 54.0% ±3.1 (n 979); Giant Graveyard 55.3% ±4.4 (n 485). Those are ladder results, not Clan War results: the planner above builds a set from your own levels.

How do I build four war decks with no repeated card?

Enter the level of each card you own (type them or paste “Hog Rider 14, Zap 13”) and press “Build war set”. The planner gives each deck a win condition first, then hands the best card for each job to the weakest deck, so no card is used twice. If you swap cards by hand, “Overlap conflicts” lists any card that now sits in two decks.

How many decks do I need for Clan Wars?

Up to four. You build 4 War Decks from your own cards; a card can be in only one of them (32 different cards). A used deck rests until local midnight. A Duel needs three of them; the decks a Duel does not use stay free.

Can two war decks share a card?

No. A card can be in only one of your War Decks, which is why four decks hold 32 different cards.

A Duel is best of 3 with three different War Decks; a tie after the tiebreaker is decided by a coin flip. Decks you did not need stay free.

When can I reuse a war deck?

After it rests: the 2020 Clan Wars 2 post says a used War Deck is free again at local midnight. In “Deck cooldowns” you mark the decks you have played and the page counts down to your device’s midnight — it is a calendar, not read from your account or clan.

Can I build war decks without Evolutions?

Yes. The planner fills each deck with eight ordinary cards from your levels and never forces an Evolution, so a collection without any still gets four legal decks. Whether the same Evolution may appear in two war decks is not stated in the Supercell posts we read, so check the in-game deck screen.

Does the planner need my player tag?

No. The tag field is optional and is not sent anywhere — this page cannot read your account. Enter your card levels in the details table or paste them as “Hog Rider 14, Zap 13”; they stay in this browser.

Boat Battles and Boat Defenses

Boat Defenses: A clan sets up 10 to 15 Boat Defenses (depending on its league); each has 3 Defense Towers loaded with 4 cards. Towers only summon troops once damaged. Destroying one tower wins a Boat Attack. Supercell post · since 2020-08-31 · checked 2026-10-24 source

Training Days, Medals and Movement Points

Training and Battle Days: Since the summer 2021 update the first 3 days of the week are Training Days (practise, earn Gold, set up defences); the Battle Days that follow earn Medals. Supercell post · since 2021-06-07 · checked 2026-10-24 source
Movement Points: Medals earned by the clan decide its rank each Battle Day, and the rank pays Movement Points that move the boat. Every standing Boat Defense adds more each day; a destroyed one stays down until the week ends. Supercell post · since 2021-06-07 · checked 2026-10-24 source

Show 8 answers ▾

What are the best Clan War decks?: From the decks we counted (1 Sep – 24 Oct 2026, top Path of Legends players), the four that share no card and score best once each win rate is cut by its margin are Lava Miner 56.7% ±3.5 (n 765); Minion Giant Control 58.1% ±5.4 (n 320); Spell Bait 54.0% ±3.1 (n 979); Giant Graveyard 55.3% ±4.4 (n 485). Those are ladder results, not Clan War results: the planner above builds a set from your own levels.
How do I build four war decks with no repeated card?: Enter the level of each card you own (type them or paste “Hog Rider 14, Zap 13”) and press “Build war set”. The planner gives each deck a win condition first, then hands the best card for each job to the weakest deck, so no card is used twice. If you swap cards by hand, “Overlap conflicts” lists any card that now sits in two decks.
How many decks do I need for Clan Wars?: Up to four. You build 4 War Decks from your own cards; a card can be in only one of them (32 different cards). A used deck rests until local midnight. A Duel needs three of them; the decks a Duel does not use stay free.

Can I build war decks without Evolutions?: Yes. The planner fills each deck with eight ordinary cards from your levels and never forces an Evolution, so a collection without any still gets four legal decks. Whether the same Evolution may appear in two war decks is not stated in the Supercell posts we read, so check the in-game deck screen.
