Eldrazi Displacer + Blessed Sanctuary + Ashnod's Altar + Anointed Procession

Eldrazi Displacer

Blessed Sanctuary

Ashnod's Altar

Anointed Procession

How it works

1. Activate Eldrazi Displacer by paying 2C, blinking any other nontoken creature you control.
2. When the creature enters the battlefield, Blessed Sanctuary triggers, creating two 2/2 Unicorn creature tokens.
3. Activate Ashnod's Altar twice by sacrificing the Unicorns, adding CCCC.
4. Repeat.

This clever engine loops by leveraging the synergy between Eldrazi Displacer's repeatable exile-and-return ability and Ashnod's Altar, which funds the blink cost with interest. Every time your blinked creature returns, Blessed Sanctuary spots the entry and spawns a Unicorn token, a process dramatically supercharged by Anointed Procession doubling your output into a pair of tokens instead of one. Sacrificing those two tokens to Ashnod's Altar generates four colorless mana, leaving you with a surplus to feed back into Eldrazi Displacer while safely letting Blessed Sanctuary shield your board from incidental damage along the way.
