This page explains how to defeat Elite Four Flint.
Flint is the third member of Sinnoh’s Elite Four, who specializes in Fire-types… or he wishes, if Sinnoh had enough Fire-types! This will be fixed during his rematch though. For now, just smile and pretend not to notice.
Elite Four Flint
First up is Rapidash, which is one of only two Fire-types in Flint’s team. It can use Flame Charge for STAB and to boost its already high Speed, Iron Tail to hit Rock-types and Poison Jab just in case. It can also use Hypnosis to send your Pokémon to sleep. Take it out with Water or Ground-types if you can. Avoid hitting it directly due to Flame Body.
Steelix isn’t a Fire-type, but it’s weak to Water-types, which counts for something, maybe? This one can use Iron Tail for STAB, Thunder Fang to punish Water-types, Fire Fang to annoy opposing Steel-types and Crunch, because why not? Thanks to its Life Orb and Sheer Force, its attacks will hit hard, but we’d be surprised if it survived a single Water or Fire-type special move.
Drifblim is a lot of hot air…? Anyway, this ghoul can be extremely annoying with Minimize to boost its evasion, Strength Sap to lower your Attack and restore its health, Will-O-Wisp to burn (and lower your Attack) and Baton Pass to pass on its evasion boosts. Avoid physical attackers and use an Electric-type with Shock Wave (cannot miss) if you have one.
Lopunny has Fire Punch. Besides that, it can use High Jump Kick to damage Rock and Steel-types, Mirror Coat to bounce back damage from special moves and Quick Attack to sneak in a first strike. Naturally, Fighting-types are its bane. Otherwise, it’s not particularly strong.
Finally, Infernape is a honest-to-goodness Fire-type, as well as Fighting-type. It’s packing Fire Punch and Close Combat for STAB (the latter dealing massive damage, at the cost of its defenses), Thunder Punch to counter Water and Flying-types and Mach Punch to strike first. Note that it’s carrying a Focus Sash, which prevents it from being KO’d in one hit. We recommend answering with a Psychic or Ground-type.
