You see, if you cast a spell that sets up an effect that happens "at end of turn" once you've past the start of the end-of-turn step, you can keep the results of that spell around until the next end-of-turn step
Added Death Troopers
Value-oriented Persists will likely end up picking up Sire of Insanity, or another Modern Horizons 2 bomb, Archon of Cruelty
Im actually surprised that I dont see this card more often in Commander because its equal parts efficient and effective
Overall, it's a much more versatile batch of cards than this grab-bag of Hatsune Miku planeswalkers - some are good in Commander, but you also have the Modern card Living End, as well Careful Study, which sees a little bit of Legacy and Pauper play
But these counters also represent Domris toughness, so if your opponent attacks Domri and the card suffers damage, you lose one counter for every point of damage sustained
