Rhox Pummeler

Six power for six mana on a three-toughness frame is a body most removal answers for free and most blockers trade up against, which is exactly the fragility this design is built to sell you around. What it hands you is one guaranteed swing: the shield counter absorbs the first damage or destruction that would be dealt to the Rhino, and the trample is welded to that same counter, so the first exchange both peels the shield and strips the evasion in one motion. After that you are left holding the vanilla 6/3 the stat line promised, a creature that dies to a stiff breeze. The whole card is front-loaded: attack now, punch through blockers now, and accept that the second turn out of this creature is a much smaller card. The counter rewards a preemptive swing before the opponent can spend removal, and it punishes patience, because a held-back attacker is a 6/3 that loses its shield to the first thing that looks at it. Where the design earns its keep is against sweepers and targeted kill spells, which the counter shrugs once, making this a reasonable body to jam into open mana. But the reward never repeats. The shield is a single-use pass, not a permanent buff, and the trample being tied to it means the trick only fires once. Everything about this creature is engineered to make that first attack count and to make the rest an afterthought.
