Infiltrate

Strategy

 * As shown in the picture, your Infiltrate bonus applies to the first four columns from your opponent's starting side. Avalanche is the first four columns on your starting side.
 * The spell Glacial Fissure deals 8 damage to everything in the central column.
 * You can also use Walls and Provoke to block your opponent from running out of the Infiltrate zone so you can continue to use your Infiltrate bonuses!
