How it works

3. Activate Crystalline Crawler's first ability by removing a +1/+1 counter from it, adding .

This clever engine locks down your opponents' boards by weaponizing the tap ability of Ballynock Trapper, which you can constantly refresh thanks to the blue mana generated by Crystalline Crawler. Every time you activate the Trapper to tap an opponent's creature, Solitary Sanctuary triggers to place a +1/+1 counter back onto the Crawler, replenishing its cost. Meanwhile, Freed from the Real provides the magical lubrication to untap the Trapper for the precise amount of blue mana produced by that very same counter removal, creating a self-sustaining loop that can completely neutralize your foes' attackers turn after turn.
