'Avishkar' cards

At the beginning of combat on your turn, until end of turn, each noncreature, non-Vehicle artifact you control becomes a 5/3 Vehicle in addition to its other types and gains trample, haste, and crew 2. Whenever chaos ensues, return target noncreature artifact card from your graveyard to your hand.

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.
