mtg angel tribal commander deck an : r/custommagic not an official Wizards of the Coast product. Avacyn, Angel of Hope ANGEL

You get to sneak in an artifact or creature, and then when it eventually leaves play, it acts as a board wipe equal to its mana value

That adds some insurance policy to your more aggressive plays as those looking to swing with characters will need to get past Baloo, Von Bruinwald XIII first, and those looking to sweep the board with big and dangerous songs like Grab Your Swords and Be Prepared will risk pushing the game in your favour, or even handing you the win

Gifts Ungiven for Pulse of Murasa, Kayas Guile, Lightning Helix, and Eternal Witness would be nice

One more item that Ive encountered that may end up being super relevant: The uncommons from the Set/Theme Booster exclusives are ONLY in those specialized boosters
