Pushed a follow-up commit with line fixes found while replaying games against the built-in AI decks:

• Accesscode Talker now only uses Selene + 1 monster as material. Before it could consume up to 4 bodies to reach Link-4, which stripped the whole board for one beatstick.
• Master of Chaos is now preferred over Dark Magician the Dragon Knight when its ② board wipe converts into lethal damage, and its ② also fires with a single blocker when that swing is lethal.
• The Dark Magicians ②: the Dark Magician / Dark Magician Girl it revives during the opponent's battle phase are summoned in defense when the opponent controls a 2500+ ATK monster. They used to come back in attack position and die immediately.
• 朔夜时雨 (52038441): only negates effect monsters that are not already negated (Normal monsters and already-negated monsters are skipped).
• Magicians' Salvation: activates to set Eternal Soul from the deck when Eternal Soul is not covered yet, instead of holding the card forever.
• Soul Servant: also usable while Dark Magical Circle is still in hand.

All changes were validated locally on a srvpro arena (2 tables, 100~300 games per configuration).
