just if anyone else got excited to see this guy and only found out he wasn't working at all after making the deck (made a neat one around him with perilous myr, rancor and spine of ish sah to make an army of tokens). this is a workaround that works perfectly as long as you don't cheat. I've added a line to reduce the opportunities for cheating - more could be added for combat step/each step immediately after a main phase but as long as you as the player dont cheat this can do exactly what the card should be able to do.
