Idyllic Grange

The design bargain here is stated plainly: accept the tapland tempo hit most of the time, or clear the count of three-plus other Plains and staple a free +1/+1 counter onto the fixing. That conditional turns a mana source into a soft payoff for committing hard to a single basic type, which is the point of the cycle it belongs to. The wrinkle is that the counter triggers on the land entering untapped, not on the land play itself: hit the threshold on a normal main-phase drop and it is a permanent buff on the way down; but anything that puts the land onto the battlefield untapped through other means carries the trigger with it, so the bonus is not categorically locked out of surprise timing. What separates it from an ordinary comes-into-play-tapped land is where the reward lands: the counter goes on a creature you already control, so the payout only exists once a board exists to grow. Early, it is a Plains that costs you a turn of speed. Once the threshold is met, it upgrades a body while it fixes. That asymmetry taxes the greedy early curve and rewards the mono-white build that was never going to splash anyway. It asks nothing of your spells and the trigger is one-shot: a single counter, once, not a repeatable engine. A land dressed with a small stapled bonus, built for the deck that would rather run a fifth relevant permanent than a strictly better dual.
