Prowling Serpopard

Hatebears that lock something down usually trade size or speed for the lock they impose; this one refuses that bargain. A 4/3 for three mana beats down on rate even when its text never matters, which is the whole point: the card asks nothing of the green deck it sits in except the it costs to hardcast, and in return it shuts off the single line that punishes a creature-based plan hardest. The clause protecting itself first is the load-bearing detail, since a control opponent's instinct is to counter the anti-counter creature on the way down. By covering the spell that grants the protection, the design closes a loop that earlier "your creatures can't be countered" effects left open, where the umbrella arrived too late to save the body carrying it. Note the asymmetry in the second line: only your creature spells get the protection, not your noncreature spells, which keeps it from becoming a blanket "you can't counter anything" effect and preserves the counterspell as a live tool against your own ramp and removal. The result is a piece of green's long-running argument with blue, where green's answer to permission has rarely been to outwit it on the stack but to deploy a threat permission cannot touch and then attack with it.
