Spectacular Skywhale

Most spellslinger payoffs cash their trigger the same way every time: a flat pump, a scaled burst, a token, resolved and forgotten by cleanup. This one splits the reward by size instead, and that fork is what gives the card its shape. A cheap cantrip lifts power for the turn and vanishes at end of turn; a spell cast with five or more mana permanently grows the whale with three +1/+1 counters, banking the gains between turns rather than resetting them each cast. The threshold asks a spells deck to decide, spell by spell, whether it wants a single-turn swing or a compounding clock, and it pins the compounding path to exactly the spell size such a deck is already reaching for by the midgame. The 1/4 body is what makes the patience viable. Four toughness on a flier stonewalls early attackers and buys time to reach the heavier spells, and the same permanent that blocked in the opening turns becomes an evasive finisher once those spells start landing and the counters accumulate. It is a payoff engineered to survive its own slow start: a wall while the deck is setting up, a threat once it is online, without ever swapping which card it is.
