Why Expensive Cards Win on Boat Defense
Boat defense towers recharge elixir about four times faster than normal in dated guides. A 9-elixir card costs far less than it looks, so the cards that are too heavy for a normal match are exactly the cards to use.
Our first list covered the top five picks: 5 best boat defense cards. This list adds five more that work well, especially when slots are in the right order. If the mode itself is new to you, the Clan Wars 2 guide explains how defenses fit in.
Why it matters: boat defenses use your own card levels. A well-picked set holds up against stronger clans, and a weak one gives free wins away.
The trend in boat defense is toward heavier, slower pushes, because the towers can afford them. The negative effect: the more clans copy the same heavy defenses, the easier it gets for attackers to learn the counters, and the old picks lose value quickly.
The 5 Best Boat Defense Cards (Part 2)
1. Mega Knight
Why it works: it was a close call between Mega Knight and P.E.K.K.A. for first place. The Mega Knight (7 elixir) counters a push more efficiently, because his range reaches both the tank and its support. Nobody sends troops one by one into a boat defense, so pushes are the norm.
The catch: air units and single-unit tank-killers beat him.
Pair it with: ranged damage like Musketeers to cover that.
2. P.E.K.K.A.
Why it works: the P.E.K.K.A. (7 elixir) is a tank and a tank-killer in one card. It rips down tanks and shields its allies from attacks. In a one-on-one fight it usually beats Mega Knight and Giant Skeleton.
The catch: Inferno cards and swarms counter it.
Pair it with: splash units or electro cards. Or swap in Giant Skeleton to get the death bomb.
3. Three Musketeers
Why it works: ranged units are a must in boat battles, and the Three Musketeers (9 elixir) bring a lot of damage. Together they rip down any tank, ground or air. At the enemy tower, one or two volleys can bring it down.
The catch: they are glass cannons.
Pair it with: a beefy unit in an earlier slot.
4. Royal Recruits
Why it works: the Royal Recruits (7 elixir) are often forgotten, but six units with shields are more than most defenders can handle. They counter most tanks.
The catch: Mega Knight is one of the few good answers to them. He is probably the card that activated your tower in the first place.
Pair it with: P.E.K.K.A., to be safe.
5. Wizard
Why it works: the Wizard is a reliable splash card. He costs 5 elixir in a normal match, but less than two elixir on a boat defense tower. Most boat battle decks use Clone, and a lone Wizard can take down a whole push.
The catch: hard hitters like Prince, Elite Barbarians and Mini P.E.K.K.A. can beat him.
Pair it with: a tank like Giant Skeleton or P.E.K.K.A. in the slot before him. The Executioner works as a substitute for similar value.
Longer term, expect boat defense lineups to spread between clans through video guides and clan chats, the way war decks do today. The negative effect: when every clan runs the same lineup, attackers learn the counters, and the “best” set quickly becomes the easiest to beat.
How to Pair These Cards
The best boat defense lineup combines tank, damage and cover. Here is a simple chart:
| Card | Elixir | Role | Weakness | Pair it with |
| Mega Knight | 7 | Push stopper | Air units, single tank-killers | Musketeers |
| P.E.K.K.A. | 7 | Tank and tank-killer | Inferno cards, swarms | Splash units |
| Three Musketeers | 9 | Ranged damage | Fragile | A tank in the earlier slot |
| Royal Recruits | 7 | Tank counter | Mega Knight | P.E.K.K.A. |
| Wizard | 5 | Splash damage | Prince, Elite Barbarians | Giant Skeleton or P.E.K.K.A. |
Quick example: slot one Giant Skeleton, slot two Wizard, slot three Mega Knight, slot four Three Musketeers. The tank soaks, the Wizard clears swarms, Mega Knight stops the push and the Musketeers finish it.
Boat defenses will likely keep rewarding heavy pairs like this one. The negative effect: if Supercell lowers boat-tower recharge speed, 9-elixir cards stop being a bargain overnight, and clans with only one lineup will have no backup plan.
To level the cards you use, check the card upgrade costs page first. Each card needs different resources, and Epics and Legendaries take the longest.
