At the beginning of your end step, create a Treasure token for each tapped Assassin, Pirate, and/or Vehicle you control. Whenever a Vehicle you control deals combat damage to a player, look at the top card of that player's library, then exile it face down. You may play that card for as long as it remains exiled.

Creatures you control are every creature type. The same is true for creature spells you control and creature cards you own that aren't on the battlefield. {3}, {T}: Create a 2/2 blue Shapeshifter creature token with changeling. (It is every creature type.)

Creature and planeswalker spells you cast have affinity for artifacts. (They cost {1} less to cast for each artifact you control.) +2: Tezzeret deals X damage to each opponent, where X is the number of artifacts you control. You gain X life. −3: Return target artifact card from your graveyard to your hand. −8: Exile the top ten cards of your library. Put all artifact cards from among them onto the battlefield.
