Untap effects like Thousand-Year Elixir, Seedborn Muse, and Tyvar, Jubilant Brawler turn the Night Witch into an engine by letting you activate it multiple times a turn cycle, plus all that sacrificing pairs well with Midnight Reaper
Excess Damage Lethal damage is the exact amount of damage you have to deal to kill a creature, planeswalker, or battle.
