How it works
Activate Emry by tapping it, targeting Mishra's Bauble.
Cast Mishra's Bauble from your graveyard by paying 0.
Displacer Kitten triggers, blinking Great Oak Guardian.
When Great Oak Guardian enters, it triggers, untapping all creatures you control and giving them +2/+2 until end of turn.
Activate Mishra's Bauble by tapping and sacrificing it.
Repeat.
This loop turns the modest utility of Mishra's Bauble into an engine of endless iteration by leveraging Emry, Lurker of the Loch to recast the artifact from your graveyard over and over. Every time you cast that free noncreature spell, Displacer Kitten triggers to blink Great Oak Guardian, whose enter-the-battlefield ability untaps Emry so she can repeat the process indefinitely. The result is a compounding cascade of artifact sacrifices, creature untaps, and massive stat boosts that will leave your opponents buried under your infinite resources.
