Mist Leopard

Shroud was once green's default way to protect an attacker, and this is that idea at its most stripped down: a 3/2 for whose only printed wrinkle is that nothing can touch it, friend or foe. The catch baked into the keyword is that you can't touch it either. No Giant Growth to push it through, no aura to dress it up, no targeted regeneration when it trades poorly. So an evasion-less body for four mana becomes a sealed unit: it attacks, it blocks, it dodges every targeted removal spell pointed at it, and that is the whole transaction. The math rarely works out, because four mana for a 3/2 sits below curve even with the protection, and shroud's symmetry means it scales worse than hexproof would in any deck that wants to build around its creatures. That is precisely why later design largely abandoned shroud on creatures in favor of hexproof, which keeps your own pump and combat tricks legal while still walling off the opponent's removal. As a piece of color-pie history it reads as an honest, slightly underpowered teaching card: here is what untargetability costs you, written plainly on a Cat. The lineage runs forward to creatures that learned to keep the upside without paying the full tax.
