Naya

The whole gimmick of this plane is that it hands you Naya's founding drug: land, land, and more land. The static ability that lets you play any number of lands per turn is a mechanical translation of Alara's most fertile shard into a rules effect, and the chaos trigger that follows makes that land count matter, pumping a Naya-colored creature by its size. It is a plane that models a color-identity philosophy directly: Naya was the shard built around gigantism, where creatures with high power counted as spells for their affinity-style payoffs, and the design here restates that as "the more lands you sit on, the larger your beast swings." The land-per-turn clause is doing the heavy lifting, since it turns every draw step into a potential ramp turn and rewards a deck stuffed with extra lands the way the shard's flavor always wanted. The chaos payoff is deliberately narrow (red, green, or white only), a fenced-off buff that keeps the plane loyal to its shard rather than a generic combat trick anyone can abuse. As a piece of multiplayer scaffolding it works best in exactly the kind of grindy, board-heavy games where land counts climb into double digits, at which point the +1/+1-per-land clause can hand a single creature a genuinely lethal swing out of nowhere.
