Gravetide Deck (EDH / Commander)

> Combo #1

Start with a creature in play and Buried Alive + Victimize in your hand.

• step #1: cast Buried Alive and put Mikaeus the Unhallowed + Triskelion (and whatever other creature you like) into your graveyard.
• step #2: cast Victimize (sacrificing the creature in play) to reanimate them.
• step #3: remove a +1/+1 counter from Triskelion to deal 1 damage.
• step #4: remove 2 counters from Triskelion to kill itself (it's a 2/2 because of Mikaeus's pumping effect).
• step #5: Triskelion comes back with 1 more counter because of undying.
• step #6: remove all counters to kill Triskelion and deal 2 more damage.
• step #7: repeat from step #5.

Same as combo #1, but with Intuition instead of Buried Alive.

• step #1: cast Intuition and search for Mikaeus the Unhallowed + Triskelion + Undead Gladiator.
• step #2: if your opponent picks Undead Gladiator, go to step 2 of combo #1. Otherwise, use Undead Gladiator to discard the combo piece in your hand and continue as before.
