Derevi, Empyrial Tactician + Emiel the Blessed + Storm the Vault // Vault of Catlacan

Derevi, Empyrial Tactician

Emiel the Blessed

Storm the Vault // Vault of Catlacan

How it works

1. Activate Vault of Catlacan's second ability by tapping it, adding at least .
2. Activate Emiel by paying 3, blinking Derevi.
3. When Derevi enters the battlefield, it triggers, untapping Vault of Catlacan.
4. Repeat.

This ingenious loop relies on Vault of Catlacan—the transformed side of Storm the Vault—generating an abundance of blue mana with every tap, scaling with the artifacts you control. Emiel the Blessed acts as the engine, using its activation cost to blink Derevi, Empyrial Tactician out of existence and right back in. Every time Derevi, Empyrial Tactician enters the battlefield, its triggered ability untaps Vault of Catlacan so you can repeat the process, leaving you with infinite mana and endless enter-the-battlefield triggers.
