The 4 combo pieces

What must be in place

Lurking Roper has at least one +1/+1 counter on it and does not have summoning sickness.

How to execute it

  1. Activate Lurking Roper using Kiki-Jiki's ability by tapping it, creating a token copy of itself with haste.
  2. When the Lurking Roper token enters the battlefield, Prosperous Innkeeper's second ability triggers, causing you to gain 1 life.
  3. Each Lurking Roper you control triggers, untapping themselves.
  4. Repeat.
  5. You may also target any nonlegendary creature you control, including Prosperous Innkeeper.
