Five mana for a 4/5 sits under the rate the legendary uncommons and equipment-wielding commons set at the top of this curve, so the body alone isn't the sell. Ward 3 is. In a medium-speed format where the removal commons are one-for-ones that already trade time for cards, taxing Grounded for Life or Stomped by the Foot by three mana is often the difference between answering the threat on curve and answering it two turns too late. The opponent still gets the trade if they want it; they just pay a tempo premium that a GU Tempo deck is built to exploit, sticking a clock while the answer sits stranded behind the tax.
That resilience is real but conditional. Bot Bashing Time still kills it, but paying three extra mana on a sorcery is a brutal turn for a red deck, which is exactly the point: ward doesn't stop removal, it makes removal expensive enough that the opponent often routes around it instead. The failure case is racing. A board built on Sneak and trample would rather ignore a 4/5 than overpay to kill it, and ward does nothing against a creature the opponent never targets.
The home is GU Tempo or a mono-green stompy shell that resolves the hybrid cost cleanly and wants a threat the first removal spell can't cleanly answer. P1P5 to P1P7 in those colors, maindeck when your five-slot isn't already crowded by a legendary bomb. Against the dedicated removal decks it's at its best; against the racers it's a 4/5 that ate a pick slot. Read the table before you commit it.
