Veraline, Regal Spellblade

Prowess (Whenever you cast a noncreature
spell, this creature gets +1/+1 until end of turn.)

Carian Retaliation — {1}{u}{r}, {t}: Counter target spell or ability. If a spell is countered this way, Veraline deals damage equal to its power
to that spell's controller. Activate only once
each turn.
