How it works

3. Activate Oboro Breezecaller by paying 2 and returning a tapped Island to your hand, untapping another Island.

This elegant blue loop transforms the mana-doubling power of High Tide into an endless engine by turning your lands into a self-sustaining resource. With High Tide supercharging your basic Islands, you can tap them for massive mana reserves while Oboro Breezecaller helps bounce and reset those lands to your hand. Walking Atlas rapidly drops those returned lands right back onto the battlefield to keep the cycle going, fueling the mana needed for Pemmin's Aura to constantly untap Walking Atlas.
