This intricate token-and-counter loop centers around Lullmage Mentor, whose activated ability counters an opponent's spell at the steep cost of tapping seven untapped Merfolk you control. However, every time Lullmage Mentor's counter ability resolves, its own reflexive trigger rewards you with a Merfolk token, which is where the true alchemy begins. Because Elspeth, Storm Slayer, Exalted Sunborn, and Anointed Procession feature replacement effects that amplify token creation, that single token-making trigger instead floods your board with eight fresh Merfolk at once. This exponential payout instantly replaces the seven tappers you spent, leaving you with a surplus of untapped bodies to fund the Lullmage Mentor again and completely lock your opponents out of resolving any spells.
