megas and z-moves cobblomon

megas and z-moves cobblomon (server-side Cobblemon addon for 1.21.1)

• Drops a server initializer that wires into Cobblemon’s held-item system and battle request sanitizing so every eligible species can Mega Evolve or use Z-Moves without needing to hunt down every stone or crystal. If a Pokémon isn’t already holding a recognized item, the mod supplies a virtual mega stone for its species (covers all official megas; Charizard/Mewtwo pick X vs Y based on higher Attack vs Special Attack) or a type-appropriate Z-Crystal chosen from its current moveset and STAB.
• Players automatically receive the required key items (Key Stone and Z-Ring) via both the Cobblemon default key item list and on data sync, ensuring Showdown’s request sanitizer never blocks gimmicks.
• Uses virtual items only; real held items that Cobblemon already understands stay untouched, and nothing is consumed/removed from inventory when a gimmick triggers.
• Bundled mega coverage: Venusaur through Diancie, including split-form species (Charizard, Mewtwo) and every other official mega line.
• Z-Move support uses the standard 18 type crystals to expose compatible Z-Moves for any damaging or status move; signature crystals beyond the type set are not injected, so signature-only Z-Moves still require their specific crystals if you add them separately.

Usage: place the jar in the server’s mods folder. Mega evolution buttons and Z-Move tiles will appear automatically in battles once Cobblemon is present; no extra commands or item distribution are needed.
