Jaheira, Friend of the Forest

The line "Tokens you control have ': Add '" reframes an entire archetype's board from a threat count into a mana pool. A go-wide deck normally spends its Saprolings, Servos, Squirrels, and Birds on a single anthem payoff or an alpha strike; here each of them also floats green, and a spread board starts working the way a Gaea's Cradle does, laid flat across the battlefield. Creature tokens still owe a turn to summoning sickness before they tap, but noncreature tokens (Treasures, Clues, Foods, and their kin) come online the moment they hit play, adding an immediate burst on top of the aggregate creature output. That dual role is the design bet: at one green apiece no single token is worth much, but enough of them out-ramp a conventional artifact package while still threatening lethal, so the deck can build toward an overloaded wrath survivor, an X-spell, or the next haymaker without ever choosing between offense and mana. As a mono-green legendary with Choose a Background, her flexibility does not come from a second color on her own line; it comes from the second command-zone slot, which lets her borrow sacrifice payoffs, untap tricks, or additional color access from a Background rather than a third card holding the strategy together. She herself is a modest druid parked at three mana; the value is in what she does to the twenty tokens standing behind her, positioning a go-wide deck at a mana ceiling those decks rarely reach.
