The 3 combo pieces

What must be in place

You control a permanent that is boosting the toughness of all your creatures by at least 1, or that is giving a creature a +1/+1 counter as it enters the battlefield.
You control at least one additional creature.

How to execute it

  1. Activate Shilgengar by sacrificing Tom, Bert, and William.
  2. When Tom, Bert, and William die, they trigger, returning them from your graveyard to the battlefield as a noncreature artifact.
  3. Because Tom, Bert, and William enter as a noncreature artifact, March of the Machines will then cause Tom, Bert, and William to be a 5/5 artifact creature.
  4. Resolve the Shilgengar ability.
  5. Repeat.
  6. Activate Shilgengar's first ability by sacrificing another creature, creating a Blood token.
  7. The Blood token enters the battlefield as a 0/0 creature due to March of the Machines, and will have its toughness boosted by the permanent specified in the pre-requisites to prevent it from dying.
  8. Repeat.
