Secret Identity

Two combat tricks stapled to a single blue mana, pointing at the same creature and resolving opposite problems. The Conceal half is a defensive dodge: shrink your own creature to a base 1/1 and wrap it in hexproof, dropping it out of range of a targeted removal spell or rewriting what it trades with once a block is declared. The Reveal half is the aggressive gear: a base 3/4 with flying and vigilance, an evasive body that can swing and still hold the fort. One card either asks the board to leave your creature alone or forces it to deal with a suddenly airborne threat, the choice made in response to what the opponent has already committed. Both modes set base power and toughness rather than handing out a bonus, and the layering carries real consequences: setting base P/T (layer 7b) resolves before power/toughness modifications (layer 7c), so a +1/+1 counter still applies on top (a base 1/1 with a counter lands at 2/2), but so does a -X/-X debuff, meaning Conceal will not rescue a creature already caught under a shrink effect and may hasten its death instead. The instant-speed window is where the value sits: hold up one mana, then pick vanish or punch once the trade is set up.
