i really dont think your kabutops would survive a bullet punch from a choice banded adamant/careful scizor with max atk investment. tyranitar might with its bulk. to check rotom-w you can use charizards solarbeam, just hope the rotom isnt wearing a CS / misses its hydro pump.
to be honost im just not a big fan of tyranitar or weather teams. ive seen alot of them, ofc the politoed / ludicolo combo and tyranitar/exadrill/garchomp. but theyre so easy to beat that i just cant recommend using them. my talonflame pretty much ohko every ludicolo ive ever faced and landorus-t or superpower/play rough azumarill pretty much take care of most tyranitars. lets not forget mega-aerodactyl running iron head, which i always do.
, it looks awesome and it has its uses but gen 6 just has too many threats for it.
the point is Scizor is one of tyranitars more likely counters so fire punch or fire fang would be good to check that threat. fire blast would be a bad suggestion. low accuracy + its a special attack while tyranitar is mainly a physical attacker. its tricky to find a good moveset for tyranitar with all the threats but i think Gallade, Scizor, Lucario, Landorus-T, Keldeo, Mega-Lopunny, Milotic, Serperior are some of your more common threats. but you could also replace stealth rock for more coverage. id run dragondance and send it in against a talonflame or something to force a switch so you can set up. scizors sometimes tend to switch out on tyranitar since theyre not confident of a ohko and fear a fire move. steel types have become very desirable to counter fairy types.
also i see you use pursuit to counter ghost types but most ghosts are gengar and they can learn focus blast,
my gengar
252 sp. atk
252 speed
timid
wide lens
Focus blast
shadow ball/dazzling gleam/psychic
thunderbolt/energy ball
sludge bomb/sludge wave

im not here to suggest anything im just here to inform you of the obvious points you seem to have overlooked.
Drain punch chestnaught might also pose a threat but theyre not as common as scizor or ferro.

what im trying to say is that looking at your team i would probably win 4-0 anyday and im being generous ive beaten similar & better teams with 5-0 / 6-0 by switching at the right time i usually end up with 3 or 4 damaged but 0 ko'd mons
