If you guys have pokebank, go download your Meganium, Typhlosion, and Feraligatr with their Hidden Abilities!
Meganium's Leaf Guard Hidden Ability protects the Pokémon from status conditions when sunlight is harsh or extremely harsh. Plus, this Meganium knows the move Sunny Day, allowing it to take advantage of its own Ability!
Typhlosion has the Flash Fire Hidden Ability, which powers up Fire-type moves by 50% and prevents this Pokémon from taking damage from Fire-type moves. With three strong Fire-type moves already in its arsenal, Typhlosion can make the most of Flash Fire in battle.
Feraligatr's Sheer Force Hidden Ability eliminates the additional effects of this Pokémon's attacks, but they will do an additional 30% damage instead. This Feraligatr knows three moves that have additional effects: Ice Punch, Crunch, and Waterfall. They won't cause their additional effect, but they'll all do huge damage!
If you do not have pokebank, post and I'll try my best to get you a breedject or two
