Start populating the board with cheap cards such as Ant-Man and Squirrel Girl right from the start. Ka-Zar should be used to boost these cheap units, and then Onslaught should be played to double their strength at the right turn. The strategy is centered on broad board visibility. This way, when you play Onslaught, you have multiple low-cost cards active on the field, and his effect will affect all of them.
