Colossal Heroics

Strive turns a combat trick into a scaling pump spell, and this one bolts an untap clause onto the back of the +2/+2. That untap is the load-bearing word. Most pump tricks ask only when you want the buff to land; this one stacks a second question on top. Cast it in the declare blockers step and you get both halves at once: the +2/+2 pushes combat damage through, and the untap leaves your attackers standing for the crackback (untapping a creature does not pull it out of combat, so it deals its damage and is still up to block). The Strive cost prices the spell to the board it serves: each additional target adds , so a one-target cast is a cheap surprise that reads as pseudo-vigilance, while spreading it across a wide team is an alpha strike that keeps everything defensively relevant. Folding a power boost and an untap into a single instant collapses an effect green usually splits across two cards, and that combination is what makes the timing flexible: there is rarely a point in the turn where one half or the other is dead. The untap also feeds anything that cares about tapping (mana dorks, tap-to-activate creatures), giving the spell a second life outside combat. Built for the green deck that goes wide and wants its attackers honest on both swings of the same turn.
