This brilliant synergy transforms Experiment Kraj into an ultimate engine by placing a +1/+1 counter on Ley Weaver, allowing it to inherit the land-untapping ability while Soliton's blue-mana untap ability is similarly assimilated. By tapping Experiment Kraj to untap two lands (including one that produces blue mana), you generate the exact resource needed to pay for Soliton's self-untap ability, resetting Experiment Kraj to repeat the loop endlessly. Because Ley Weaver provides the untapping power and Soliton provides the active untap mechanism, you can effortlessly cycle between them to generate infinite mana of any color your lands can produce. As a magnificent bonus, Experiment Kraj's own tapping ability lets you spread infinite +1/+1 counters to every other creature you control along the way.
