Moment of Valor
The two halves answer opposite battlefield states, and the split is what keeps this from being filler. The first mode is a combat and protection trick: untap a blocker to double-block or ambush, hand it indestructibility to walk it through targeted removal or a losing block, and nudge the power up to push the extra point through. The second mode is a conditional kill that only fires on power 4 or greater, priced to police the big threats the trick cannot beat in a fight. That threshold is the pivot: against a wide, small board the destroy half is a dead card and you fall back on the trick, while against a single fatty the trick is the weaker line and you reach for the kill. Modal cards like this trade raw efficiency for the guarantee that at least one half is live almost anywhere, which is why the rate on either mode reads unremarkable in isolation. Holding it at instant speed is where the value hides: the opponent has to respect both a protection blowout and a clean answer to their biggest creature, and cannot know which until the mana is spent. What it punishes is overcommitment on both ends of the size curve, folded into one white instant.
