Whitewater Naiads

Evasion-as-an-engine is a strange home for a constellation payoff, and that mismatch is what makes the design worth a second look. Most enchantment-trigger cards from this era bank small increments (a counter here, a point of life-drain there) each time a permanent lands. This one instead hands out a single point of unblockability, retargetable on every trigger, which means its value scales not with board state but with how many enchantments you can deploy in a turn. The timing is the whole strategic axis: the trigger asks for permanents entering, not for a combat decision, so it rewards a proactive main-phase build that resolves enchantments before attacks rather than a reactive one holding up answers to blockers. Cast a run of auras and enchantment creatures during your precombat main phase and you can point unblockability at a different attacker each time, all of it live for the full turn's combat step. In a deck dense with cheap enchantments, the 4/4 body becomes almost incidental; the real output is a recurring "this attacker connects" stapled to each permanent you play. The body is itself an enchantment, so it triggers off its own arrival, pushing one creature through even in an otherwise creature-heavy shell. The ceiling lives entirely in the subtheme, though: a constellation trigger with no follow-up enchantments points at one attacker and stops. The tension is that a mechanic built around amassing static permanents gets bent here into a relentless offensive clock.
