Calamity, Galloping Inferno + Biovisionary + Kaya, Geist Hunter

Calamity, Galloping Inferno

Biovisionary

Kaya, Geist Hunter

How it works

1. Activate Kaya's second loyalty ability by removing two loyalty counters from it, causing you to double any tokens you create this turn.
2. Activate Calamity's saddle ability by tapping Biovisionary, causing Calamity to become saddled until end of turn.
3. Declare Calamity as an attacker.
4. Calamity triggers, creating four token copies of Biovisionary that are tapped and attacking.
5. At the beginning of your end step, Calamity triggers four times and each Biovisionary triggers.
6. Resolve the first Biovisionary trigger, causing you to win the game.

This clever replication loop harnesses Kaya, Geist Hunter's minus ability to double token creation right before you ride into battle. When you saddle Calamity, Galloping Inferno with Biovisionary and declare an attack, Calamity's triggered ability would normally make two copies of the creature that saddled it—but thanks to Kaya's proactive boost, you instead flood the board with four fresh copies. When the end step arrives, you will control the requisite quorum of identical wizards, allowing Biovisionary's static-checking triggered ability to instantly claim victory.
