Llanowar Tribe

Take the humble one-mana Elf and scale everything by three: the body becomes a 3/3, and the tap adds three green instead of one. The catch is baked into the triple-green casting cost. This is an accelerant that only functions inside a deck committed hard to green, often a mono-green one, and that constraint is what buys the rate. A one-drop that adds a single mana can slot into any manabase; a three-drop that demands GGG to cast and then, once it can tap, returns GGG only pulls ahead in the abstract, since summoning sickness means it does nothing the turn it arrives and the ramp starts paying out a turn later. The design bet is that green decks big enough to want three extra mana per turn are also decks that can reliably assemble triple green, and that the durable 3/3 frame (a real blocker, a real attacker, resilient to incidental damage) earns its keep in the games where the ramp is redundant. It sits in a lineage of green accelerants that scale their output to color commitment, closer in spirit to Priest of Titania or Elvish Archdruid than to the one-drop it echoes, but without asking you to count other Elves. What you get is a fixed, dependable burst that rewards building deep into a single color rather than wide across many.
