Grand Warlord Radha

The mana doesn't come from tapping; it comes from declaring an attack. That reframing is the whole engine. Most ramp asks you to commit resources before the turn pays off: rocks, dorks, rituals that empty your hand into a payoff that may never land. Radha inverts the order. The board you've already built is the source, and the act of swinging with it generates a pool scaled to how wide you've gone. Three attackers means three mana, ten means ten, and the persistence clause is what turns the trick into a strategy: that mana survives the combat step's emptying, so it's still there in your second main phase to recast, reload, or fire off something that ends the game while the opponent is tapped low from blocking decisions they've just made. The friction is that it asks you to attack into open boards to bank the most mana, which puts the creatures you're trying to leverage at risk in the same breath. Green-red's history is littered with creatures that try to be both the beatdown and the value engine; this one resolves the tension by making the beatdown be the engine, paying you in exact proportion to your willingness to send the team. The 3/4 body with haste matters here too: it can attack the turn it lands, meaning the mana flows immediately rather than waiting a rotation for the legend to survive a removal window.
