Skywatcher Adept

A Merfolk Wizard that converts surplus mana into a body you never have to discard: that is the whole proposition, and it is the cleanest demonstration of growth-curve design fit onto one card. Cast for a single blue, it sits as a 1/1 with no evasion, then absorbs mana three at a time to climb its track. The first investment is the one that changes the most: it adds a point of toughness and, crucially, flying, so the very first upgrade buys the keyword the base body lacks. After that the trajectory bends in only one direction, power rising toward four while toughness stays pinned at two, with no second ability and no defensive cushion arriving along the way. Because leveling resolves at sorcery speed, the upgrade is always telegraphed; you commit during your main phase and hand the opponent a window to kill the body before it grows. That sorcery-speed restriction is what marks it as a mana sink rather than a combat trick or a build-around. The 4/2 ceiling tells you exactly what the leveling buys: a faster evasive clock, not survivability, so the card stays a glass cannon that loses any fight it picks. This is the unglamorous end of a mechanic that elsewhere produced rattling engines and combo enablers. Here the entire ambition is a flier that refuses to rot in your hand once you have mana to spare.
