Glint

The toughness bump is the tell. Most protection tricks in blue lean entirely on bounce or counterspells; this one stays in combat, granting hexproof to keep a creature off targeted removal while the +0/+3 lets it survive the block it just walked into. The pairing is deliberate: hexproof shuts the door on the spot-removal answer, and the toughness handles the damage-based answer, so a single two-mana instant covers both vectors at once. The asymmetry of the stat line matters too. Nothing is added to power, which signals what the card is for: it is a defensive insurance policy, not a way to push extra damage through. You hold it up to protect a creature that is already doing the work (a value engine, an evasive threat carrying an aura) rather than to win a race. That narrow remit is also its ceiling. Without offensive upside it never threatens to two-for-one, and the hexproof reaches only one creature at a time, leaving your other threats to fend for themselves; it answers a specific question (will my key threat survive this turn) cleanly and asks nothing more.
