If you are duoing Tyranitar, please use 6 Machamps. 2 people is the BARE minimum and they must have the perfect balance between power and durability because when you finish the battle you should only have like 5 seconds left. Hariyama is lacking in power, and especially since most of your stuff have close combat, it's going to have a hard time.
Tyranitar Duo Cloudy
Hi everyone
i'm looking to duo Ttar in future, do you think my team is ready to deal 50% TDO, if boosted by weather cloudy?

What about this?
Machamp 2455 A15
Machamp 2297 A10
Hariyama 2353 A14
Hariyama 2345 A13
Machamp 1683 A15
Machamp 1627 A14
All C/DP.
Pokebattler says even the last 2 Machamps (L20.5 and L20) can clear Ttar in 340s against the Bite movesets. With the stronger Machamps carrying them, they should be fine.
The other player:

Hariyama 2421 A15
Hariyama 2423 A09

Also all C/DP.
Close Combat is way too slow to be featured on more than 1 counter when trying to duo Ttar even when it's cloudy (unless they are much higher levels). All your counters are definitely high enough level and IV right now if they had C/DP, but right now they don't have fast enough moves.
Additionally, I'd make sure you have a second team lined up to go because you are going to want to avoid dodging if you can and just plow through it. C/FB Blaziken above Lv thirty (preferrably closer to 35) is a better option than C/CC champ/hari. Don't bother with Breloom, it is waaaaay to glassy for this even with C/DP.
