Galvanize

Two mana for three damage to a creature is the honest baseline that spells like Lightning Strike and Abrade have held for years; the escalation clause is what makes Galvanize worth building around, and where it points is the interesting part. The extra two damage isn't gated behind ramp, counters, or a color pip: it's gated behind a turn where you've already drawn two cards, which aims the reward squarely at spellslinger and cantrip-heavy shells. A single extra draw before you cast it (a cheap cantrip, a looter's trigger, a second card off any draw-two effect) turns a middling removal spell into one that answers nearly anything a creature can put on the board. The design discipline is that the bonus is retroactive to the whole turn rather than an on-cast trigger, so you sequence your draws first and hold the card up at instant speed, deciding whether you've earned five damage only once a target commits. That framing separates it from raw efficiency: it rewards a play pattern you were already running, without asking you to track a permanent, learn a keyword, or splash a color. It is a threshold-style payoff wearing a burn spell's clothes, priced at the base rate for everyone and generous only to the deck built to trigger it.
