Joraga Treespeaker

Level Up folded an entire curve into a single one-drop, and this is the cleanest case of a floor-to-ceiling design the keyword produced. It arrives as a 1/1 that does nothing the turn it lands, then asks you to spend later sorcery-speed windows converting mana into level counters instead of developing your board. Hitting the first level is the moment it earns its keep: a creature plus a activation, three mana in total, to unlock a body that taps for two green and starts replacing its own cost like a second land. Levels two through four hand you nothing new at all (the body stays a 1/2, the mana output stays put), so they read as a pure toll on the way to five rather than incremental ramp. The whole payoff lives at the top: at level five the engine fans out across the board, granting every Elf you control that same two-green tap, so a field of mana dorks doubles its yield in a single graduation. That ceiling is what turns it from curve-filler into a build-around, and the dead middle levels are the price of the ceiling. Because Level Up is sorcery speed but not once per turn, you can dump every available mana into it the moment your hand is empty and race the climb in a single window, gambling that the 1/2 survives a removal spell long enough to graduate. It sits in the line of green mana-Elf payoffs that reward flooding the board: most Elves add their mana once, while this one eventually teaches the rest of the room to do it too.
