Homarid Spawning Bed + Mystic Reflection + Scholar of the Ages + Phyrexian Altar

Homarid Spawning Bed

Mystic Reflection

Scholar of the Ages

Phyrexian Altar

How it works

1. Cast Mystic Reflection by paying 1, causing the next creatures or planeswalkers to enter the battlefield this turn to enter as copies of Scholar of the Ages.
2. Activate Homarid Spawning Bed by paying 1 and sacrificing Scholar of the Ages, creating seven token copies of Scholar of the Ages.
3. Each of the newly created Scholar of the Ages tokens triggers, returning Mystic Reflection and up to thirteen other instant and/or sorcery cards from your graveyard to your hand.
4. Activate Phyrexian Altar six times by sacrificing six Scholar of the Ages tokens, adding 3.
5. Repeat.

This ingenious loop starts by using Mystic Reflection to turn an ordinary entry event into a cascade of clones, setting up Scholar of the Ages to flood the board with duplicate triggers. Because each newly created token enters as another copy of Scholar of the Ages, their entry triggers let you continually fish Mystic Reflection and other powerful spells right back out of your graveyard. Meanwhile, Phyrexian Altar acts as the engine's sacrificial altar, turning your surplus tokens into the exact colored mana needed to pay for Homarid Spawning Bed and recast your setup. The Spawning Bed itself converts that mana—and a high-mana-value creature sacrifice—into a massive swarm of Camarids, ensuring you can repeat the entire cycle indefinitely for infinite mana, infinite tokens, and total graveyard recursion.
