Lotus Cobra

The acceleration trick is that the trigger fires off any land entering, not just the one you play for turn. That distinction is the entire engine: a fetchland cracks for two mana of any color, a land-bounce effect replayed becomes a loop, and an extra-land enabler turns a single creature into a ramp battery. The "any color" clause means it fixes and accelerates on the same trigger, doing in one slot what a Birds of Paradise style dork splits into a single job. It scales not with how many lands you draw but with how greedily a deck can sneak them into play, which is why its ceiling sits in the lands package rather than the creature itself. The 2/1 body is fragile to the point of being a liability: a one-time landfall trigger evaporates if the snake is dead before you crack a fetch, so sequencing matters (resolve it, then trigger it the same turn you can spend the mana, rather than telegraphing it a turn early). What makes the design distinctive is its open-endedness. Most ramp creatures cap their output deliberately, buying a fixed amount of acceleration for their cost. This one refuses to set a number: two mana buys a trigger, and how much that trigger is worth is left for the deck around it to decide.
