Recharge is an exceptionally powerful event that is a must-play in every game. Not only does it provide 2 Voltswappers, which already makes it a very good event, Shock Recovery offers great value. During Recharge turns, the strategy is to go all out, flooding the board with Voltswappers to create massive circuits. While there are occasions where you might use one Recharge just to get 2 Voltswappers, you should try to maximize your Recharge turns in every game, generally along with Overcharge.
