Remembrance + Mortuary + Phyrexian Walker + Bloodflow Connoisseur

Remembrance

Mortuary

Phyrexian Walker

Bloodflow Connoisseur

How it works

1. Activate Bloodflow Connoisseur by sacrificing Phyrexian Walker.
2. When Phyrexian Walker dies, Mortuary and Remembrance trigger.
3. Resolve the Mortuary trigger, putting Phyrexian Walker from your graveyard on top of your library.
4. Resolve the Remembrance trigger, searching your library for Phyrexian Walker and putting it into your hand.
5. Resolve the Bloodflow Connoisseur ability, putting a +1/+1 counter on it.
6. Cast Phyrexian Walker by paying 0.
7. Repeat.

This elegant loop turns the free, zero-mana casting cost of Phyrexian Walker into an engine for endless growth and triggers. When you sacrifice the Walker to Bloodflow Connoisseur, Mortuary immediately intercepts it in the graveyard to place it back on top of your library, while Remembrance simultaneously lets you tutor another copy straight to your hand. Because Phyrexian Walker costs zero mana to recast, you can immediately replay it and repeat the entire sequence to pile an infinite number of +1/+1 counters onto your Connoisseur.
