mardu mtg cards SAVAI Red/White/Black Commander Deck Builder Starter Pack Kit – CommanderComplete Activate only as a sorcery Mardu bomb : r/custommagic

I also value its built-in card draw as a handy tool over the course of the game, and more useful than a conditional finisher being in the command zone

It's even got a two-word title

You have plenty of flash threats at your disposal, so when your opponent plays around a Derevi activation, you might actually be planning to ambush them with Restoration Angel or remove their threat with Venser, Shaper Savant

The drawback here is a creature or artifact sacrifice, but in today's game with treasure and other artifact tokens plentiful, this may not be so painful

While there are a few spells to deal with the combo (Cleansing Wildfire, Waking the Trolls) overall it is two hard of a combo to interact with for some decks
