Gaining infinite life by turn 4 consistently is awesome. Then midgaming infinite mana for either a fireball from hell, or infinite DMG from impact tremors or aetherflux res.

I'm still not sure on the sideboard.

HOW IT WORKS!

Infinite life

A sister and curio on the field+ 2 mana etb creatures.

There are actually a few ways to do it in this deck.

Infinite mana

Curio + panharmonicon + 2 mana generators.

Infinite recursion/draw

Infinite green mana generation + curio+ eternal witness/visionary

Edit, swapped to RW instead of naya
