mtg witherbloom commander deck Secrets of Strixhaven 10 double Secrets of Strixhaven: Commander -

All of your good removal like Open Fire, Puncturing Blow, and Unquenchable Thirst is going to trigger these cards as well as cheap cantrips in the form of Crash Through and Strategic Planning

Lands that tap for multiple mana like Ancient Tomb can come back untapped to accelerate your big plays, permanents like Gilded Drake that you traded away to an opponent let you ensnare another big creature, or you can simply retake something stolen by an Agent of Treachery

Plus, graveyard hate or timely counters can throw your entire rhythm off

There are better token anthems out there, but this background helps to keep your deck on-budget
