Playful Shove

Red rarely gets to draw a card without paying for it somewhere, so the design lever here is how small the payload is. One damage is not a removal spell in any meaningful sense: it clears a mana dork, pings a one-toughness utility creature, finishes a chump attacker, or goes to the face when nothing better presents itself. The point is that the damage never has to matter. This is a cantrip first, dressed as a ping, and the ping is the tax red pays to touch the card-advantage well the color is otherwise walled off from. That framing changes how you value it: you are not asking whether one damage answers a threat, you are asking whether a two-mana cantrip that occasionally trades up is worth a slot. The touchstone is Shock as a rate, but the closer relatives are the small red cantrips built to smooth curves and keep hands flowing rather than to kill anything. Spell-for-spell it looks unimpressive, and reads very differently once you count how many dead draws it quietly converts into live ones.
