Bloodsoaked Champion + Bridge from Below + Pitiless Plunderer + Phantom Train

Bloodsoaked Champion

Bridge from Below

Pitiless Plunderer

Phantom Train

How it works

1. Activate Phantom Train by sacrificing Bloodsoaked Champion.
2. When Bloodsoaked Champion dies, Pitiless Plunderer and Bridge from Below trigger, creating a creature token and a Treasure token.
3. Resolve the Phantom Train ability.
4. Activate Phantom Train by sacrificing the creature token.
5. When the creature token dies, Pitiless Plunderer triggers, creating a Treasure token.
6. Resolve the Phantom Train ability.
7. Activate the Treasures by tapping and sacrificing them, adding 1.
8. Activate Bloodsoaked Champion by paying 1, returning it from your graveyard to the battlefield.
9. Repeat.

This clever engine transforms a relentless recursive attacker into an infinite loop by leveraging death triggers and mana generation. Whenever you feed Bloodsoaked Champion or a Zombie token to Phantom Train, Pitiless Plunderer steps in to generate a Treasure token that refunds the mana required to bring the Champion right back via its raid ability. Meanwhile, Bridge from Below rewards every nontoken creature death by continuously churning out 2/2 Zombie tokens to keep the sacrifice chain fueled, steadily pumping the Train full of infinite +1/+1 counters.
