Pia Nalaar, Chief Mechanic

Whenever one or more artifact creatures you control deal combat damage to a player, you get {E}{E} (two energy counters).

At the beginning of your end step, you may pay one or more {E}. If you do, create an X/X colorless Vehicle artifact token named Nalaar Aetherjet with flying and crew 2, where X is the amount of {E} paid this way.
