Lathril, Blade of the Elves - Intelligence

Build a wide Elf board, help Lathril connect in combat, and turn those tokens into mana, card advantage, or a ten-Elf life-drain finish.

Lathril creates Elf Warrior tokens equal to the combat damage she actually deals to a player.

If Lathril deals combat damage to a player in both first-strike and regular combat damage steps, each damage event can trigger separately.

Menace means Lathril cannot be blocked except by two or more creatures; it does not guarantee combat damage.

Activating Lathril's drain normally requires tapping Lathril plus ten other untapped Elves you control.

The ten Elves tapped for the additional cost may have summoning sickness, but Lathril must have haste or have been controlled continuously because her own tap symbol is used.

The activated ability makes each opponent lose life and you gain life; it does not target and it is not damage.

Curve one-mana Elves into Lathril, then use lords and token makers to pressure the table while keeping enough bodies for drain turns.

Make Lathril connect by using menace pressure, blocker removal, power boosts, and protection.

Keep a large Elf board untapped or reusable so Lathril can drain every opponent for 10.

Use Elf mana engines and optional sacrifice payoffs while keeping Lathril's Elf density intact.
