Emry, Lurker of the Loch + Displacer Kitten + Urza's Bauble + Mass Hysteria

Emry, Lurker of the Loch

Displacer Kitten

Urza's Bauble

Mass Hysteria

How it works

1. Activate Emry by tapping it, allowing you to cast Urza's Bauble from your graveyard.
2. Cast Urza's Bauble by paying 0.
3. Displacer Kitten triggers, blinking Emry.
4. When Emry enters, it triggers, causing you to mill four cards.
5. Activate Urza's Bauble by tapping and sacrificing it.
6. Repeat.

This ingenious loop transforms Urza's Bauble into a self-replenishing engine by leaning on the persistent speed granted by Mass Hysteria to bypass summoning sickness. Every time you cast the Bauble from your graveyard using Emry, Lurker of the Loch's activated ability, Displacer Kitten triggers to blink Emry—freshly untapping her with her new entry and triggering a fresh round of self-milling to feed the loop. Because the Bauble costs nothing to cast, you can endlessly repeat this sequence to cycle through your deck, churn out infinite triggers, and set up an overwhelming storm count or draw advantage for the next upkeep.
