Fly? The opponent gets a free turn or gets a free switch...

Tanks aren't sweepers... Tanks are pokemon that can absorb hits, like walls, but can hit back hard.

Well,
1). Make Tyranitar your lead. And replace Gaga Impact with something else.  
2). Guillotine isn't a good idea, theres not a very good chance that it will hit.
3). You're missing your EVs- EVs are very crucial.

Rio, I believe this has been commented towards you several times.
EVs are replaceable by roles according to the rules.

Right. Got that now. ;P

Answer 1

Hydreigon is great but get rid of Draco meteor because it ruins your sweep. Give it tri attack and you can cut down a stat and give them a status condition.

For mandibuzz you should get rid of fly for acrobatics and give him a flying gem.

For tyranitar get rid of giga impact for earth quake. You can do more damage.

For krookidile you need to get rid of thunder fang for outrage which will do much more damage.

Drapion is good so keep it.

For Crawdant get rid of gullitine, it will never hit. Replace it with superpower.
