Yes. Cobblemon is a required dependency, and Cobblemon: Mega Showdown is an optional companion that the pack depends on for its Mega mechanics.

Is the pack compatible with older builds of Cobblemon: Mega Showdown?

Only newer builds work. Older builds of the pack do not function with the newer Mega Showdown releases, so players should match versions.
