Pia Nalaar, Chief Mechanic (Borderless) #2

Whenever one or more artifact creatures you control deal combat damage to a player, you get EE (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 Atherjet with flying and crew 2, where X is the amount of E spent this way.
