Lathliss, Dragon Queen + Bladewing's Thrall + Arcane Adaptation + Phantom Train

Lathliss, Dragon Queen

Bladewing's Thrall

Arcane Adaptation

Phantom Train

How it works

1. Cast Bladewing's Thrall by paying 2.
2. When Bladewing's Thrall enters the battlefield, Lathliss triggers.
3. Holding priority, activate Phantom Train by sacrificing Bladewing's Thrall.
4. Resolve the Lathliss trigger, creating a 5/5 Dragon creature token.
5. When the Dragon enters the battlefield, Bladewing's Thrall triggers, returning itself from your graveyard to the battlefield.
6. Repeat from step 2.

This clever engine turns your graveyard into a perpetual hatchery by transforming your non-Dragon threats into heavy-scaling apex predators. With Arcane Adaptation naming Dragons, every creature you own—including Bladewing's Thrall and Phantom Train—enters as a Dragon, allowing Bladewing's Thrall to continuously resurrect itself from the graveyard whenever a Dragon enters. Meanwhile, Lathliss, Dragon Queen watches these recurring entrances to flood the board with an endless swarm of 5/5 Dragon tokens. You sacrifice the freshly returned Bladewing's Thrall to Phantom Train's activation cost to keep the loop going, stacking infinite +1/+1 counters onto the Train while generating boundless sacrifices and death triggers.
