Queen Brahne
A prowess creature that spends its own trigger twice. The +1/+1 that noncreature spells grant is the smaller half of the reward: the real engine is the attack trigger, which manufactures a fragile 0/1 Wizard that carries a second copy of the prowess-shaped condition. Cast a noncreature spell after the attack and every Wizard token she made pings each opponent for one, so the same instants and sorceries that pump the body also convert into a scaling reach clause that stacks with each attack step. The 2/1 frame is the tension: a one-toughness attacker into open mana is a coin flip, and the payoff only pays after she has already committed to combat, so the sequencing question is whether you have a spell to cast on the attack or one to hold for the token damage, rarely both cheaply. That splits the card's noncreature spells into two competing jobs (protect the body now, or bank the burst for the swing) and the deck has to decide which it wants each turn. It reads as a go-wide token payoff wearing the clothes of a spellslinger enabler, and the friction between those two identities (needing bodies on the board and needing cheap spells in hand at the same time) is what keeps the rate from being oppressive despite how quickly the damage compounds once the tokens accumulate.
