mtg are unfinity cards legal in commander MTG Unfinity Get Your Head the Game 10 Regular Uncommon Is the new Unfinity set

Optimus Prime, Hero / Optimus Prime, Autobot Leader +1/+1 counters is a less common theme for Jeskai, but you can pair Optimus Prime, Hero with creatures like Abzan Falconer and Envoy of the Ancestors to gain access to strong keywords, and Lae'zel, Vlaakith's Champion to boost counter production

That does mean you wont get to keep the monarchy for long, but if you can, you can annihilate your opponent with your horde of Humans

The more tests a card passes, the safer you can feel about its legitimacy
