Najeela, the Blade-Blossom + Rith, the Awakener + Phyrexian Altar

Najeela, the Blade-Blossom

Rith, the Awakener

Phyrexian Altar

How it works

1. Declare Rith and Najeela, if desired, as attackers.
2. If one or more Warriors attack, Najeela triggers, creating that many 1/1 Warrior creature tokens.
3. Deal combat damage using Rith.
4. Rith triggers, causing you to pay 2 to create at least eight 1/1 Saproling creature tokens.
5. Activate Phyrexian Altar five times by sacrificing five Saprolings, adding .
6. Activate Najeela by paying , untapping all attacking creatures, giving them trample, lifelink and haste, and gaining an additional combat phase after this one.
7. Move to your next combat phase.
8. Repeat steps 1-3 one additional time.
9. Rith triggers, holding priority, activate Phyrexian Altar three times by sacrificing three Saprolings, adding 2.
10. Resolve the Rith trigger, causing you to pay 2 to create at least eight 1/1 Saproling creature tokens.
11. Repeat from step 5.
12. If there are at least nine permanents of any color on the battlefield and/or you control a Warrior that can attack, this combo nets infinite creature tokens and colored mana.

This explosive loop is fueled by Najeela, the Blade-Blossom, whose activation creates an endless sequence of combat phases while simultaneously pumping out attacking Warrior tokens whenever any Warrior swings. Rith, the Awakener plays a massive supporting role by crashing in for combat damage and cashing in that success to flood the board with Saproling tokens based on the color density of the battlefield. Finally, Phyrexian Altar acts as the crucial engine that turns those fresh Saprolings into the exact five-color mana required to pay for Najeela's untap-and-combat ability over and over again.
