Snakeskin Veil

Green's protect-and-grow trick has always fought a design tension: it wants to be a combat pump, a counter-adder, and a hexproof shield in one card, and most attempts pay for that breadth with an ungainly cost. This one folds all three into a single mana at instant speed, and that price is what makes the timing so punishing. Held up as a bluff, any untapped green mana becomes a threat: aim point removal at the target and it slips away with a bigger body; walk into the block and the counter rewrites the math. The hexproof is transient, a reactive shield that expires with the turn, but the +1/+1 counter it leaves is the part that sticks. That permanence is the quiet reason it plays better than a straight protection spell in decks that care about counters: the same cast that saves your creature also advances a board built on proliferate, +1/+1 payoffs, or evolve triggers, so even a "wasted" answer leaves value behind. It is the natural green reply to a targeted kill spell, cheap enough to keep in hand every turn without warping a curve, and it rewards the aggressor for keeping mana up rather than the control player for holding it back.
