Best Arena 4 DecksSpell Valley

Same reliable Giant-tank shell as earlier arenas with a stronger spell suite once Fireball is unlocked, trading Zap/Log flexibility for one big spell that can swing a defense.

Save Fireball for a defensive punish — a well-timed Fireball on a grouped push can single-handedly win the elixir trade and set up your counter-push.

Fireball is your only heavy spell in this deck, so don't waste it clearing small chip damage — a two-card push from your opponent isn't worth it.

Lead with Archers behind the tower to start banking elixir toward your first Giant push.

Valkyrie's 360-degree splash wipes out swarms that would otherwise chip your tower for free, and Tesla adds a defensive building that survives most single-target pushes.

Let Tesla handle single tanks and win conditions on defense while Valkyrie mops up any swarm troops accompanying them — then push with whichever troops survive.

Valkyrie is expensive for a purely defensive card — don't play it reactively against troops your cheaper cards (Archers, Minions) could have handled instead.

Place Tesla centrally on your first meaningful defensive read so it can hit either lane.

Ice Golem adds a cheap, tanky defensive option in front of Hog Rider pushes, keeping the deck's average elixir low enough to out-cycle slower opponents while still tanking a hit or two.

Use Ice Golem to soak the first hit against incoming pushes, then immediately follow with Hog Rider once you've stabilized — the goal is to always be a cycle ahead.

Ice Spirit's freeze effect is short — don't count on it alone to fully stop a fast push; pair it with Cannon or Ice Golem rather than using it in isolation.

Cycle Ice Spirit first — it's cheap enough to throw away purely for information on your opponent's opening.
