Sword Coast Serpent // Capsizing Wave

Split across two turns, this card asks a blue deck to do exactly what it was already doing. Capsizing Wave is the cheap side you lead with: a bounce that clears a blocker, resets a token attacker, or steals a tempo swing against a developing board, and the Adventure's exile clause parks the 6/6 for a later cast. The evasion on the creature half keys off any noncreature spell cast that turn, not off the Adventure itself: once the serpent is down, a cantrip, a counter, or a removal spell earlier in the turn is enough to send it in unblocked. The wording matters. It is a static "as long as" condition, not a triggered one, so it reads the board at the moment you attack: put a noncreature spell on the stack at any point that turn and the evasion is simply on. And it does have to be a spell going on the stack. An activated ability, a mana tap, a loyalty tick: none of those satisfy the condition no matter how much noncreature activity crosses the table. That distinction is the card's one real cost, and it is a cheap one. A blue deck burns most of its turns casting noncreature spells anyway, so the evasion arrives less as a build-around than as a byproduct: shape the board early, recast the body later, and let a spell you were casting regardless carry six power past the ground.
