Nowhere to Run
The interesting move here isn't the -3/-3, which is a fine flash-speed answer to most early creatures on its own. It's the second half: a persistent clause that switches off both hexproof and ward on every creature your opponent controls, for as long as the enchantment sits on the battlefield. Removal spells that care about evasion have usually paid for it once, at the moment of casting, and then evaporated. This one leaves the door open. The kill trigger clears an immediate threat, and the enclosure stays behind, so every subsequent spell and ability you point at those creatures lands as though those defensive keywords were never printed. That reframes the card from a one-shot answer into a standing license. The distinction between hexproof and ward matters to how completely it does the job: hexproof is turned off by making the creatures legal targets "as though they didn't have hexproof," while ward is neutralized by suppressing the trigger outright, so no tax, no counter, no life payment fires. Two different rules problems, solved by two different clauses in the same sentence. The result is a piece of interaction that punishes the entire category of "you can't touch my threats" strategies rather than a single creature, and the flash timing lets it ambush a protected attacker mid-combat while the ongoing effect quietly disarms whatever the opponent commits next.
