Bane's Invoker

Eight mana for a two-mana body's activated ability is the tell: this is a Baldur's Gate background-flavored take on the old "cheap creature with an absurdly expensive mana sink" design, where the printed pump is real but priced so far out that the two-power body is what you actually get for most of the game. Wind Walk here is not a keyword doing evergreen work; it is the flavor name pasted onto a mana sink, and the sink costs more than the whole rest of a low-curve board is likely to. The effect it buys (up to two creatures each getting +2/+2 and flying until end of turn) is a legitimate alpha-strike enabler, splitting the buff and evasion across two attackers to punch through a stalled ground. But the gates it to the very late game, and by then two extra power and temporary flying on a pair of bodies rarely closes what a real finisher would. The honest read is a cheap white creature that fills a curve slot and holds an emergency reach-for button you press once a game, if ever. It fits a go-wide white shell that expects to flood the board and needs a way to jump the last few points over a blocker, and does very little anywhere the buff never gets paid for.
