The 2 combo pieces

What must be in place

An opponent controls seven or more creatures.

How to execute it

  1. Cast Canker Abomination by paying {2}{B/G}{B/G}.
  2. When Canker Abomination enters the battlefield, it triggers, putting a number of -1/-1 counters on it equal to the number of creatures an opponent controls.
  3. Canker Abomination dies as a state-based action due to having 0 or less toughness, triggering its undying ability, returning it from your graveyard to the battlefield with a +1/+1 counter on it.
  4. Repeat from step 2.
