Several Mardu Commander strategies want to attack every time they can, and that’s what makes Kamigawa: Neon Dynasty’s Isshin, Two Heavens as One such an incredible card to play. This three-mana 3/4 doubles the attack triggers of your permanents, which means many of your best cards will give you twice the usual amount of value. It makes for an excellent Commander, but it’s also good in the ninety-nine of nearly every Mardu deck.
