High Stride

A one-mana instant that grants +1/+3 and reach reads as a pure defensive trick, and half the time that is exactly how it plays: ambush a flier, survive a swing, block above your creature's printed toughness. The untap rider is where the card stops behaving like an ordinary pump spell. Untapping a body already committed to combat lets you attack, then hold the same creature back to block on the crack-back, or free a tapped-out mana dork for a surprise activation. The +3 to toughness carries the defensive save (a much better shape for it than a symmetric +2/+2 or an offensive +3/+1), and stapling reach onto that makes it a purpose-built answer to evasive attackers. The design problem it addresses is the old limitation of the combat trick that only earns its keep on offense: adding untap lets a single card generate value on both halves of the turn cycle. It is a modest effect held together by a specific, deliberate rider, a green trick built to reward creatures with activated abilities and to punish an opponent who reads a tapped blocker as dead.
