Using Counter in Cobblemon

Counter is a physical move, so it scales off Attack against the target Defense. Give it to a Pokemon whose Attack is the higher of the two, and remember the 1.5x same-type bonus if the user is Fighting.

Check the type chart before relying on it, and look up specific targets in the Pokedex where dual-type multipliers are already worked out.
