mtg sefris commander deck Custom Guide This ability triggers only once each turn Sefris of the Hidden Ways

Thats a little more than youd pay normally when you look at Deadly Dispute and Fanatical Offering, but this basically draws three cards since you get the land, and it gets all your death triggers rolling

Whenever this Dimir commander attacks, you clash (which is a mechanic that cares about high mana value), and if you win you get to cast an expensive card for free

Prioritize haste and evasion so Balefire Dragon connects at least once and resets the board in your favor

That should be obvious, but it means youre buying a deck full of hyper-specific cards that dont translate well outside of their intended precon or strategy
