Infinitely large creature until end of turnInfinite +1/+1 counters on creatures you control
How it works
Activate Atog by sacrificing a Clue.
Lonis' third ability and Piper Wright's second abilities trigger.
Resolve the Lonis trigger, putting a +1/+1 counter on any other creature you control.
Resolve the Piper Wright trigger, putting a +1/+1 counter on Lonis.
Lonis' second ability triggers, creating a Clue artifact token.
Resolve the Atog ability from step 1, giving it +2/+2 until end of turn.
Repeat.
This clever loop turns the humble Clue into an engine for boundless growth by letting Atog feed on them to fuel your board. Each time you sacrifice a Clue to pump Atog, the shared triggered abilities on both Lonis, Genetics Expert and Piper Wright react to the sacrifice by distributing fresh +1/+1 counters. When a counter lands on Lonis, its second ability triggers to immediately replace the sacrificed Clue with a brand-new one, ensuring you never run out of fodder.
