The card has been added to the Moon server already, so initial scripting is not an issue.
Spoiler: Effect Text show Activate only as Chain Link 4 or higher and in response to an opponent's card or effect. Pay 3000 LP; Negate the activation and effects of all of your opponent's cards and effects in the same Chain also destroy them. If you have 6000 or more LP, you can activate this card from your hand by paying LP until you have 1000 instead.
Pros:
Player-side negation (against the opponent)
Can be activated from hand
The activation of the cards does not need to be negated for the card to be destroyed (for the case of
Constellar Belt-like cards)
Counters chain-based decks like Chain Burn or Paleozoic
Cons:
Expensive to use even if Set
Condition to use from hand is less likely to happen over the course of the duel, making turns 1-4 the most likely times to use from hand
Chain Links of 4 are hard to come by, if you don't make most of it yourself (which de-values its use), if your opponent goes through
SEGOC, or if your opponent is playing chain-based decks. (All of which are not common to see.)
Unless your deck gains LP consistently, you can only use 1 from your hand in any given (non-tag) duel.
