Voda Sea Scavenger

Card selection dressed up as body count. The 3/2 is filler; the enter trigger is the entire reason to run this Merfolk, and it scales on the one axis every Domain card leans on: how many distinct basic land types you can assemble across your lands. Cover a single type and it peeks at the top card, keeping or burying it, a scry with extra steps; cover four or five and it digs deep, sifting toward a land, a threat, or an answer while the rest go to the bottom of your library in a random order. That random-bottom clause is what keeps the effect from doing double duty: you look at plenty, keep exactly one, and lose the sequencing on everything else, so there is no stashing cards for a later fetch. It never draws either, which makes this pure selection with no card advantage attached. Because the whole payoff rides on how many colors of basic land your manabase runs, it wants a greedy mana base rather than a lean two-color one, an odd ask for a blue tempo creature that otherwise reads as generic. What Domain offers here is a dial rather than a fixed effect: a shallow top-of-library nudge in one shell, a dependable setup engine in another, and the count of distinct basic types you gather is the only thing that turns it.
