This crafty loop turns Thranduil the Strategist into a mana-generating engine, leaning on his own landfall ability to constantly replenish your board with fresh Elf tokens. By tapping those Elves for green or blue mana thanks to Thranduil the Strategist's static ability, you build the required funds to feed Nim Deathmantle whenever Umbral Collar Zealot sacrifices Thranduil the Strategist. Simultaneously, Faces of the Past triggers upon Thranduil's death to untap your entire squad of Elves, allowing them to tap right back into the mana pool.
