The 4 combo pieces

What must be in place

Mairsil does not have a +1/+1 counter on it.

How to execute it

  1. Activate Mairsil using Endling's third ability by paying {B}, giving Mairsil undying until end of turn.
  2. Activate Mairsil using Blood Vassal's ability by sacrificing it, adding {B}{B}.
  3. Mairsil dies, triggering its undying ability, returning it from your graveyard to the battlefield with a +1/+1 counter on it.
  4. Activate Mairsil using Triskelavus' ability by paying {1} and removing the +1/+1 counter from it, creating a 1/1 Triskelavite artifact creature token.
  5. Repeat.
  6. Once you have infinite Triskelavite tokens, you may sacrifice them to deal infinite damage to any target(s).
