Biovisionary + Helm of the Host + Abstruse Archaic + Strionic Resonator

Biovisionary

Helm of the Host

Abstruse Archaic

Strionic Resonator

How it works

1. At the beginning of your combat phase, Helm of the Host triggers.
2. Holding priority, activate Strionic Resonator by paying 2 and tapping it, copying Helm of the Host's trigger.
3. Activate Abstruse Archaic by paying 1 and tapping it, copying Helm of the Host's trigger.
4. Resolve all Helm of the Host triggers, creating three token copies of Biovisionary with haste.
5. At the beginning of your end step, each Biovisionary triggers.
6. Resolve the first trigger, causing you to win the game.

This clever setup takes advantage of Helm of the Host's combat trigger to rapidly multiply your threats in a single turn, equipping it to the original Biovisionary to start the chain. Instead of settling for just one token, you use Strionic Resonator to copy the triggered ability, and because Biovisionary is a colorless source, Abstruse Archaic can join in to copy it a second time. This yields a total of four copies of Biovisionary entering the battlefield with haste, instantly satisfying the original creature's win condition as soon as your end step arrives.
