How it works
Cast Twinflame by paying 1, creating a token copy of Felidar Guardian.
When the Felidar Guardian token enters the battlefield, it triggers, blinking any creature you control with base power 4 or greater.
When the creature enters the battlefield, Life Finds A Way triggers, creating a token copy of the Felidar Guardian token.
Repeat from step 2.
This charming loop sets off a chain reaction once you cast Twinflame to forge an initial token copy of Felidar Guardian. As that Felidar Guardian token enters the battlefield, its blink trigger targets a creature with base power 4 or greater, sending it away and right back into play to satisfy Life Finds a Way. That enchantment's populate ability then steps in to churn out a fresh token copy of the Felidar Guardian token, which immediately triggers its own entry ability and keeps the cycle spinning indefinitely.
