Cast Berserk only before the combat damage step. Target creature gains trample and gets +X/+0 until end of turn, where X is its power. At the beginning of the next end step, destroy that creature if it attacked this turn.
Pro Tip! When you deck is looking to deal as much damage as you can as possible, Berserk definitely helps! In Legacy Infect, the goal is to grow your tiny infect creatures and Berserk is a very strong finisher.
