Skulk (This creature can't be blocked by creatures with greater power.)
At the beginning of your end step, each opponent dealt combat damage this game by a creature named Gollum, Obsessed Stalker loses life equal to the amount of life you gained this turn.
Connect with Gollum at least once via Skulk to 'mark' each opponent, then spend the rest of the game gaining as much life as possible so your end step drains every marked opponent for that amount. You build a lifegain engine and stack big single-turn gains to deal lethal noncombat damage to the whole table at once.
Add fast mana (Sol Ring, dark rituals) and tutors (Demonic Tutor, Vampiric Tutor) to assemble lifegain payoffs sooner, and lean on free evasion (Whispersilk Cloak, Trailblazer's Boots) so Gollum reliably marks every opponent. Tighten the combo by pairing Exquisite Blood with Sanguine Bond/Vito as a redundant table-wipe, and include protection like Lightning Greaves and Heroic Intervention to keep your fragile commander alive between end steps.
