Ghirapur Grand Prix

When you planeswalk here, all players start their engines! (If you have no speed, it starts at 1. It increases once on each of your turns when an opponent loses life. Max speed is 4.) At the beginning of your end step, put X +1/+1 counters on target creature you control, where X is your speed. When you planeswalk away from Ghirapur Grand Prix, each player with the highest speed among players creates three Treasure tokens.
