Felidar Guardian + Deadeye Navigator + Nykthos, Shrine to Nyx

Felidar Guardian

Deadeye Navigator

Nykthos, Shrine to Nyx

How it works

1. Activate Nykthos' second ability by paying 2 and tapping it, adding at least .
2. Activate Felidar Guardian by paying 1, blinking it.
3. When Felidar Guardian enters the battlefield, it and Deadeye Navigator's soulbond ability trigger.
4. Resolve the Felidar Guardian trigger, blinking Nykthos.
5. Resolve the Deadeye Navigator trigger, repairing it and Felidar Guardian.
6. Repeat.
7. If your devotion to blue is at least five, this combo nets infinite mana.

This clever partnership turns Nykthos, Shrine to Nyx into an unstoppable engine, provided your devotion to blue is at least five. Deadeye Navigator grants its signature blinking ability to Felidar Guardian via soulbond, allowing the cat to repeatedly flicker off the battlefield and back. Each time Felidar Guardian enters, its triggered ability untaps Nykthos by exiling and returning it, resetting the shrine so you can tap it for a massive surge of blue mana. By reinvesting a portion of that mana to fuel Deadeye Navigator's flicker cost, you easily generate infinite mana of any color you have devotion to, alongside endless creature entries.
