Studious First-Year // Rampant Growth + Displacer Kitten + Stone-Seeder Hierophant + Selesnya Sanctuary

Studious First-Year // Rampant Growth

Displacer Kitten

Stone-Seeder Hierophant

Selesnya Sanctuary

How it works

1. Activate Stone-Seeder Hierophant by tapping it, untapping Selesnya Sanctuary.
2. Activate Selesnya Sanctuary by tapping it, adding 1.
3. Cast the copy of Rampant Growth from exile by paying 1, unpreparing Studious First-Year.
4. When you cast that spell, Displacer Kitten triggers, blinking Studious First-Year, which enters prepared.
5. Resolve Rampant Growth, fetching a basic land from your library to the battlefield tapped.
6. When the land enters, Stone-Seeder Hierophant triggers, untapping itself.
7. Repeat.

This ingenious loop uses Studious First-Year to repeatedly cast copies of Rampant Growth from exile, filtering your entire deck of basic lands directly onto the battlefield. Each cast triggers Displacer Kitten to blink Studious First-Year so it enters prepared anew, ready to fuel the next iteration. Meanwhile, the influx of new lands triggers Stone-Seeder Hierophant's landfall ability to untap itself, allowing it to repeatedly tap Selesnya Sanctuary for mana while Selesnya Sanctuary's bounce property is neatly bypassed by casting from exile rather than your hand.
