Lullmage Mentor

Ojer Taq, Deepest Foundation // Temple of Civilization

Anointed Procession

Elspeth, Storm Slayer

How it works

1. Whenever an opponent casts a spell, activate Lullmage Mentor by tapping seven untapped Merfolk, countering that spell.
2. Lullmage Mentor triggers, creating a total of twelve 1/1 Merfolk creature tokens.
3. Repeat.

This marvelous engine completely locks down your opponents by turning a single counterspell into an overwhelming swarm of Merfolk. When you use Lullmage Mentor's ability to counter an opponent's spell by tapping seven untapped Merfolk, its own trigger normally rewards you with just one token, but Ojer Taq, Deepest Foundation, Anointed Procession, and Elspeth, Storm Slayer stack their replacement effects to multiply that single token into an astonishing twelve 1/1 Merfolk creature tokens at once. Because you need only seven of those newly minted creatures to pay Lullmage Mentor's tapping cost, you are left with a massive surplus of tokens to recast the loop, letting you effortlessly counter every single spell your opponents dare to cast while burying them in an endless tide of creatures.
