Bloodline Necromancer + Flameshadow Conjuring + Thermopod

Bloodline Necromancer

Flameshadow Conjuring

Thermopod

How it works

1. Cast Bloodline Necromancer by paying 4.
2. When Bloodline Necromancer enters the battlefield, it and Flameshadow Conjuring trigger.
3. Resolve the Bloodline Necromancer trigger, returning a Vampire or Wizard creature card from your graveyard to the battlefield.
4. Activate Thermopod's second ability by sacrificing Bloodline Necromancer, adding .
5. Resolve the Flameshadow Conjuring trigger, causing you to pay to create a token copy of Bloodline Necromancer with haste.
6. When the token Bloodline Necromancer enters the battlefield, it triggers, returning the nontoken Bloodline Necromancer from your graveyard to the battlefield.
7. Repeat from step 2.

This clever loop relies on Bloodline Necromancer as both the recursive engine and the payoff, pulling itself or another Wizard or Vampire straight back from the graveyard whenever it enters the battlefield. Flameshadow Conjuring provides the duplication engine, turning every entry into a brand-new token copy by taxing you a single red mana. To feed that mana requirement and keep the loop self-sustaining, Thermopod sacrifices your creatures for red mana on demand, creating a seamless closed circuit that floods the board with infinite hasteing tokens, death triggers, and red mana.
