Enter the Unknown + Mystic Sanctuary + Bolas's Citadel + Zuran Orb + Icetill Explorer

Enter the Unknown

Mystic Sanctuary

Bolas's Citadel

Zuran Orb

Icetill Explorer

How it works

1. Cast Enter the Unknown either from your hand by paying or from the top of your library by paying 1 life, causing a creature you control to explore and allowing you to play an additional land this turn.
2. Play Mystic Sanctuary either from your hand or graveyard.
3. When Mystic Sanctuary enters the battlefield untapped, it triggers, putting Enter the Unknown from your graveyard onto the top of your library.
4. Activate Mystic Sanctuary by tapping it, adding .
5. Activate Zuran Orb by sacrificing Mystic Sanctuary, causing you to gain 2 life.
6. Repeat.

This ingenious loop relies on Mystic Sanctuary entering the battlefield untapped to perpetually recycle Enter the Unknown from your graveyard right back to the top of your library. Bolas's Citadel makes casting that top-decked sorcery effortless by trading your life total for mana, while Zuran Orb immediately sacrifices Mystic Sanctuary to fuel your lifegain and clear the land away. Meanwhile, Icetill Explorer provides the crucial passive foundation that lets you keep playing Mystic Sanctuary straight from the graveyard turn after turn, turning a simple recursion trick into an endless engine of blue mana, life, and landfall.
