Lullmage Mentor

Ojer Taq, Deepest Foundation // Temple of Civilization

Primal Vigor

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 elegant loop transforms a single counterspell into an overwhelming tidal wave of Merfolk by leveraging multiplicative token replacement effects. When Lullmage Mentor counters an opponent's spell using its tap ability, its triggered ability attempts to create a single 1/1 Merfolk token, but this output is amplified exponentially by Primal Vigor and Elspeth, Storm Slayer alongside Ojer Taq, Deepest Foundation to produce twelve tokens at once. Because you need only seven untapped Merfolk to activate Lullmage Mentor again, this surplus easily sustains the loop, allowing you to completely lock opponents out of casting spells while amassing an infinite army.
