Remembrance + Mortuary + Bloodflow Connoisseur + Shield Sphere

Remembrance

Mortuary

Bloodflow Connoisseur

Shield Sphere

How it works

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

This elegant engine turns a harmless artifact creature into a bottomless well of sacrifice and death triggers by creating a perpetual motion loop between the graveyard and your hand. With Mortuary intercepting your creatures as they hit the graveyard to place them right back on top of your library, Remembrance immediately capitalizes on that same death to tutor another copy directly to your hand. Because Shield Sphere costs zero mana to cast, you can continuously feed it to Bloodflow Connoisseur to pump the vampire full of infinite +1/+1 counters while racking up boundless storm count.
