Mistway Spy

Face up for a single blue, this is a fragile evasive body and nothing more: a 1/1 flyer that chips in for a point. All of its ambition lives in the disguise line. Deploy it as a warded 2/2 for three and the payoff becomes a flip you hold in reserve, unmasking mid-combat for when the board is at its widest. For the rest of that turn, every creature you control that connects with a player generates a Clue. The trigger has nothing to do with this Merfolk's own swing; it is a team-wide reward that scales with how many attackers are through, then vanishes at cleanup. There is no engine here, no repeatable card advantage, just a single ambush timed by you and cashed once. The design stacks a combat-step blowout on top of disguise's central tension, the pressure of a mana investment the opponent cannot read, and the ceiling is set entirely by sequencing: flip against a developed board and the Clues pile up; flip into an empty one and you have sunk five mana total (three face down, then to reveal) on a 1/1 flyer with a stale trigger. The reward you collect is exactly the board you had at the instant you chose to reveal.
