This is a Golgari Elf tribal deck that floods the board with cheap Elves and Elf Warrior tokens off a dense mana-elf base. Elves that tap for mana based on Elf or creature count snowball into huge turns that deploy more creatures and refill the hand. Lathril ties it together: menace hits make more Elf tokens, and once ten untapped Elves are assembled, Lathril's tap ability drains each opponent for 10. Untap effects let that ability, or the big mana Elves, fire more than once. How it wins: Repeated Lathril drains for 10 off a wide Elf board, backed up by anthem-pumped or Craterhoof-style alpha strikes and drain finishers like Skemfar Shadowsage and Torment of Hailfire. Key roles: - Elf mana engine: One-drop mana Elves into Elves and enablers that scale with Elf or creature count produce explosive mana, letting the deck dump its hand and fuel X spells and activations (Priest of Titania, Elvish Archdruid, Circle of Dreams Druid). - Token swarm: Repeatable and triggered Elf Warrior token makers, amplified by token doubling and Lathril's own combat trigger, quickly reach the ten-Elf threshold (Elvish Warmaster, Imperious Perfect, Doubling Season). - Untap and haste tricks: Untapping Lathril or a mana Elf allows multiple drains or massive mana in one turn, and haste enablers let freshly cast creatures tap right away (Seedborn Muse, Tyvar, Jubilant Brawler, Wirewood Lodge). - Creature-cast card flow: Casting and finding creatures refills the hand, including casting from the top of the library and tutoring Elves straight onto the battlefield (Beast Whisperer, Chord of Calling, Elven Chorus). - Lords and overrun finishers: Elf anthems make the swarm lethal in combat, and mass pump turns a wide board into a one-shot kill (Craterhoof Behemoth, Coat of Arms, Beastmaster Ascension). - Lands-as-forests package: Making creatures into Forests and every land a Forest turns Elves into land-untap targets and powers Forest-count effects (Ashaya, Soul of the Wild, Quirion Ranger, Yavimaya, Cradle of Growth).
