This clever loop turns your furry friends into a self-sustaining mana engine by leaning on the triggered and activated abilities of several key permanents. With Insidious Roots in play, your tokens gain the ability to tap for mana, and Maelstrom Wanderer grants your army haste so they don't have to suffer from summoning sickness. This lets you fuel The Unbeatable Squirrel Girl's expensive activation cost directly using the tapped creatures, creating an expanding horde of tokens that immediately pay for themselves.
