Mid-stage Pokemon like Deino rarely see competitive play outside of special formats. It's a waypoint on the road to Hydreigon, which is where the real potential kicks in. Psychic moves can't touch it, which offsets the 5 weaknesses somewhat. Known as the Irate Pokemon.
Deino's spread isn't flashy. Attack leads, Speed trails, 0 stats clear the bar. Tough to catch and worth 1 Attack EV, on a slow 1.25M XP grind.
It can’t see, so its first approach to examining things is to bite them. You will be covered in wounds until a Deino warms up to you.
It nests deep inside a cave. Food there is scarce, so Deino will sink its teeth into anything that moves and attempt to eat it.
Deino Weakness
VulnerableFairy, Ice, Fighting, Bug, and Dragon-type moves hit Deino for super-effective damage. Fairy hits land at 4x, so they're the biggest threat. The upside? Psychic-type moves can't touch it at all. 6 resistances give it solid defensive coverage on top of that.
Deino is the start of a three-stage chain. It evolves into Zweilous first, then eventually reaches Hydreigon. For breeding, takes forever to hatch with no compatible partners via one egg group. The evolved forms gain up to 300 total stats over Deino.
How to Evolve
Breed Deino from the Dragon egg group. Pass egg moves like Assurance, Astonish, Dark Pulse and 7 more to offspring.
Best Build
No build content available for this Pokemon in Gen 7.
Try selecting a different game/generation filter, or check back later.
Don't skip the egg moves. Deino picks up Assurance and Astonish only through breeding, and both fill gaps the natural movepool can't. STAB runs through Draco Meteor and Outrage while coverage across 8 types adds range.

Best Locations
Deino isn't fully evolved, so it's not built for competitive play. You'll want to evolve it into Zweilous to unlock its full potential. At 300 BST, it's a stepping stone rather than a team anchor.
Watch for Clefable (Fairy), Weavile (Ice), and Conkeldurr (Fighting) when using Deino. They all hit it super-effectively with STAB. Clefable is the most dangerous since Fairy moves deal 4x damage. Bug and Dragon-type attackers are also a problem. With 5 weakness types, most competitive teams carry at least one counter. At base 38 Speed, Deino won't outrun any of these threats so switching to a resist is usually the safer play.
Deino evolves into Zweilous at level 50. Deino is the base form in a 3-stage evolutionary line.
Hustle strengthens physical moves to inflict 1.5× damage, but decreases their accuracy to 0.8× — that's the one you want on Deino. It's the only ability Deino has.
Deino fills the balanced role. It's a physical attacker with base 65 Attack. Base 38 Speed is low. Priority moves or Trick Room are the way to go. And it's fragile — can't afford to take many hits.
Deino appears in 8 games, including Black & White, Black 2 & White 2, and X & Y.
Introduced in Black & White, Deino has appeared in 8 games across 5 generations. Later debuts mean fewer total appearances, but it's been a consistent presence since its introduction.
