Mimo, Master Manipulator

Your maximum hand size gets one card larger for every time Mimo has been cast this game.
Whenever you are forced to discard a card due to your end step, you may search your deck for a basic land card and put that into your hand after ending the end step phase. (This can only be triggered up to the amount of times Mimo was cast this game)
Feather, but just at the end of your end step
