Lullmage Mentor

Ojer Taq, Deepest Foundation // Temple of Civilization

Doubling Season

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 ingenious loop turns Lullmage Mentor into an impenetrable wall against your opponents' spells. When you tap seven Merfolk to activate Lullmage Mentor's counter ability, its own trigger responds by attempting to create a single Merfolk token, which is instantly supercharged by the cascading replacement effects of Doubling Season, Elspeth, Storm Slayer, and Ojer Taq, Deepest Foundation (whose Temple of Civilization back face shares this token-multiplying blessing). Instead of one token, you suddenly flood the board with twelve fresh Merfolk—far more than enough to immediately pay the cost to counter the next spell your opponent dares to cast.
