Main Wincon: WWH into Decimation
Secondary Wincon: WWH with scattershot into mirror image recursion to ping for damage, end on decimation (or just overwhelm with units). Opponents also usually forfeit once this combo comes together.
Other wincon: Just general feln strategies screaming and attack multiple times with Crunch, Gorgon Fanatic, and WWH.
Strategies: Use Master Cartographer, Crunch, Quarry, and Honor of Claws to discard WWH and Decimation. Will then want to use Haunting Scream on WWH to start comboing off.
Ice bolt, torch, and garden of omens are general control cards to help you last longer to get to your wincon.
Cabal Spymaster in market if you want to re-use WWH or Crunch's ability.
