By leveraging Ojer Taq, Deepest Foundation's spectacular replacement effect, every time Nemata, Grove Guardian uses its ability to generate tokens, you actually receive three times as many creatures. Those newly created saprolings immediately gain the ability to tap for mana thanks to Insidious Roots, cleanly refunding the exact green and generic mana needed to keep the loop going. Meanwhile, Samut, Voice of Dissent stands ready to grant haste and untap key permanents if needed, turning this engine into an overflowing cascade of creatures and mana.
