Moritte Copy Loop with Reef Worm

Step 1: Have Reef Worm on the battlefield.

Step 2: Cast Moritte of the Frost, having it enter as a copy of Reef Worm.

Step 3: When either the original or copied Reef Worm dies, it creates a 3/3 Fish token.

Step 4: If the Fish token dies, it creates a 6/6 Whale token, and if the Whale token dies, it creates a 9/9 Kraken token.

Step 5: Use Innkeeper's Talent to generate extra mana from your lands to potentially recast Moritte if needed.

Step 6: Use Spectral Interference to control opponent's blockers or attackers, ensuring your tokens can attack or defend effectively.

Step 7: Continue the token creation and growth cycle as the tokens die and are replaced with larger ones.
