Xu-Ifit, Osteoharmonist + Thornbite Staff + Bloodflow Connoisseur

Xu-Ifit, Osteoharmonist

Thornbite Staff

Bloodflow Connoisseur

How it works

1. Activate Xu-Ifit by tapping it, returning a creature card from your graveyard to the battlefield.
2. Activate Bloodflow Connoisseur by sacrificing the creature returned in step 1.
3. When the creature dies, Xu-Ifit triggers, untapping itself.
4. Resolve the Bloodflow Connoisseur ability.
5. Repeat.

This loop turns Xu-Ifit, Osteoharmonist into a relentless necromancer by exploiting its own resurrection ability; each time it taps to pull a creature from the graveyard, Bloodflow Connoisseur is there waiting to instantly sacrifice it. The secret engine piece quietly doing the heavy lifting behind the scenes is Thornbite Staff, which automatically untaps Xu-Ifit, Osteoharmonist whenever that sacrificed creature dies, resetting the whole cycle. With the Staff equipped and the Connoisseur growing larger with every iteration from its sacrifice ability, you achieve an infinite loop of life, death, and power.
