3Clash Royale card guide
Ice Wizard is a splash support troop that slows everything he hits. His direct damage is low, but he seriously slows down enemy pushes.
Place Ice Wizard next to your tower on defense to slow enemy troops, giving your tower and other cards more time to deal damage. Graveyard and control decks use him as both defense and offensive support. He also deals a small slowing blast when he's deployed.
Cards that deal with it efficiently:

This card has a hero form. The hero is active in your deck’s 2nd (Hero) or 3rd (Wild) slot. The Hero slot unlocks at Arena 5.
ElixirDeck automatically takes your unlocked evolutions and heroes into account: build your decks.
