mtg card corner radius A magic of the Universe: A hole in the rules? Is this a beta card

For Sieges, the battle must always be protected by an opponent of the controller if the protect leaves the game, the controller must instead choose a different opponent to protect it

Then, when you play any action card, you get a lore counter, letting you cycle through the same action card multiple times in a turn

Id sacrifice Composite Golem, bring it back with Nim Deathmantle and dump all that mana into a storm of spells (to go wide), or a single card like Walking Ballista/Golem Artisan to close out the game

Depart the Realm This is definitely a playable card in my opinion, and there's a weird playable loop for it, and you can just get it out of your hand and then use it when you need it

This is either better or worse than a half a Storm the Festival every turn depending on how you build your deck, and thats decent territory
