Infinite artifact ETBInfinite artifact LTBInfinite artifact sacrifice triggersInfinite +1/+1 counters on creatures you control
How it works
Activate Phantom Train by sacrificing a Clue.
Lonis' second ability and Tarrian's Soulcleaver trigger.
Resolve the Lonis trigger, putting a +1/+1 counter on any other creature you control.
Resolve the Tarrian's Soulcleaver trigger, putting a +1/+1 counter on Lonis.
Lonis' first ability triggers, creating a Clue artifact token.
Resolve the Phantom Train ability from step 1, putting a +1/+1 counter on it.
Repeat.
This delightful loop turns a simple sacrifice into a self-sustaining engine of growth and discovery. By feeding a Clue into Phantom Train, you send an artifact to the graveyard, which immediately feeds Tarrian's Soulcleaver by placing a +1/+1 counter on Lonis, Genetics Expert. That influx of counters triggers Lonis's ability to investigate, replacing the sacrificed Clue with a brand-new one and letting you distribute extra counters across your board. Meanwhile, Phantom Train grows larger and animates itself, ready to sacrifice the newly minted Clue all over again to keep the cycle spinning infinitely.
