Is Meganium Good in Ruby & Sapphire Playthrough?

AbilityOvergrow boosts Grass moves at low HP. Trade-only in RS. Meganium is the defensive Grass option with good bulk, but Hoenn has Breloom for the Fighting sub-typing and Ludicolo for the Water sub-typing. The import doesn't bring a unique profile.

Meganium Weakness
