Ya know, I feel like bringing up Zweilous, so here's my piece on it.
You know, one would think Zweilous would make a fearsome Choice Bander down in RU, and it's not hard to see the positives to it. With Hustle also boosting its base 85 Attack, with CB, an Adamant (or Brave) nature, 252 EVs, and 31 IVs, the two-headed dragon's Attack is effectively a whoppin'
663! With the low number of Steel-types in this tier, it should be rather easy (especially with Magneton in your team) to clear the way for some destruction by Outrage!
However, this thing is wracked by negatives, one of which is the double-edged sword known as Hustle. While the Attack boost is nice, the 20% accuracy drop can get very frustrating very fast. Base 58 Speed isn't outpacin' much outside the defensive field, and 72/70/70 isn't the bulkiest in the world. Finally, outside of Outrage and Crunch, Zweilous doesn't have much for coverage; in fact, it only has the Elemental Fangs and (maybe) Head Smash. Fire Fang is definitely the dragon's best coverage move, as it does at least provide unresisted neutral coverage alongside Outrage, as well as utterly destroying Ferroseed. However, their base power is only 65, and their accuracy is effectively 76%. Head Smash is definitely powerful, but it doesn't really give much coverage that the Fangs can't provide, it only has 64% accuracy, and the recoil is always a pain.
If you want to use this thing, I feel that it's best to use it in a Trick Room team with the following set:
Outrageous Power!
Brave / Choice Band / Hustle
EVs: 252 HP / 252 Attack / 4 Defense
Notable IVs: Speed (0)
- Outrage
- Crunch
- Fire Fang
- Thunder Fang / Ice Fang
