Worldfire + Hive Mind + Vampiric Tutor + Emergence Zone

Worldfire

Hive Mind

Vampiric Tutor

Emergence Zone

How it works

1. Activate Emergence Zone's second ability by paying 1 and tapping it, allowing you to cast spells this turn as though they have flash.
2. Cast Vampiric Tutor by paying .
3. Hive Mind triggers, causing each opponent to create a copy of Vampiric Tutor.
4. Holding priority, cast Worldfire by paying 6.
5. Hive Mind triggers, causing each opponent to create a copy of Worldfire.
6. Resolve each Worldfire on the stack, exiling all permanents, all cards in all hands and graveyards, and setting each player's life total to one.
7. Resolve the first opponent's copy of Vampiric Tutor, causing them to search their library for a card, put it on top of their library and lose 2 life.
8. The opponent loses the game due to having less than zero life.
9. Repeat from step 7 for each remaining opponent.

By leveraging Emergence Zone, we can set up an instant-speed catastrophe that turns Hive Mind into a lethal trap for our opponents. When we cast Vampiric Tutor at flash speed, Hive Mind copies it for everyone else, but before those copies resolve, we cast Worldfire to wipe the board, clear all hands and graveyards, and reduce every player's life total to a fragile 1. Because the Vampiric Tutor copies are still waiting on the stack, the opponents are forced to resolve them next; the life loss from Vampiric Tutor drops them below zero life while we sit safely out of reach.
