Rust Player

At the beginning of each combat, choose one —
• AK: Rust Player gains +3/+3 and vigilance until end of turn.
• Double Barrel: Rust Player gains haste and deathtouch until end of turn.
• C4: Rust Player gains +1/+0 and trample until end of turn.

At the beginning of each end step, if you control an artifact, you must sacrifice one. If you do, put a +1/+1 counter on Rust Player and each opponent loses 1 life.
