Shrieking Drake + Abaddon the Despoiler + Lotus Bloom + Barkform Harvester

Shrieking Drake

Abaddon the Despoiler

Lotus Bloom

Barkform Harvester

How it works

1. Cast Shrieking Drake by paying .
2. Shrieking Drake's cascade ability from Abaddon the Despoiler triggers, causing you to cast Lotus Bloom from your library since it is the only valid card to cast.
3. Shrieking Drake enters the battlefield, triggering itself, returning itself to your hand.
4. Activate Lotus Bloom by tapping and sacrificing it, adding .
5. Activate Barkform Harvester by paying 2, putting Lotus Bloom from your graveyard on the bottom of your library.
6. Repeat.

This clever loop relies on Abaddon the Despoiler to turn Shrieking Drake into a cascade engine, guaranteeing you hit the zero-mana Lotus Bloom straight from your library every time the Drake is cast. As Shrieking Drake enters, its own mandatory trigger bounces itself right back to your hand, resetting your ammunition while Lotus Bloom provides the blue mana to pay for the next cast. Meanwhile, Barkform Harvester quietly does the heavy lifting from the graveyard, utilizing its ability to recycle the sacrificed Lotus Bloom back to the bottom of your library so your cascade triggers never run out of targets.
