mtg samurai commander deck Isshin, Two Heavens as One Tribal Magic Elite Commander Mardu Samurai Deck

While niche, this card can be used to foil any opponent's typal strategies, boost your own (especially if you're playing the Everyone's Invited Secret Lair Commander deck) or in a number of interesting infinite combos: 11

Youll also want to block carefully around Gorehorn Raider if you can, though sometimes thatll mean blocking aggressively to prevent your opponent from freely sniping a 2/2

Because the activation cost is so expensive, you cant really surprise someone with the ability

Bartolom del Presidio should fit into an Agatha's Soul Cauldron deck, maybe with vampire buddies like Dusk Legion Duelist and graveyard finisher Voldaren Thrillseeker, if you can also manage to go wide, this can lead to a quick finish
