Yes, Tiny Leaders is awesome!

My own lil custom 40 card format is actually explicitly designed to be backwards compatible with any existing commander deck! You can just take a deck, draft from it (or just split it down the middle after a good shuffle), give one of the decks to a friend, and start playing!

Some more info here (if a little self-promo is OK, as a treat): https://scry.fish/microEDH
