The 3 combo pieces

What must be in place

You have a way to cause a creature to enter the battlefield under your control.
You control a basic Forest.

How to execute it

  1. Cause a creature to enter the battlefield under your control, which will be legendary due to Leyline of Singularity.
  2. Jedit triggers, holding priority, activate a basic Forest by tapping it, adding {G}.
  3. Activate Earthcraft by tapping the creature that entered the battlefield, untapping a basic Forest.
  4. Resolve the Jedit trigger, causing you to pay {G} to create a 2/2 Cat Warrior creature token that is legendary due to Leyline of Singularity.
  5. If you control two or more Cat Warrior tokens, put all but the most recent token into your graveyard due to the legend rule.
  6. Repeat from step 2.
