Tangela Solo Raid / Scyther & Pinsir good enough?

BB Charizard is top tier counter, so I would assume Scyther.

Is that a Scizor or Scyther? It is probably not the Zards fault. No Flareon?

I assume you mean Scizor since Scyther does not reach that high of a CP.
The answer is clear if you look at DPS or TTW rankings, Scizor is not a viable counter, it can at best keep you even with the clock at level 40. Whereas BB Charizard is viable from level 30 up.

Definitely Scizor, even more so if it actually is Scyther who was used and your CP value is wrong. If you don't have a L30 Flareon to use at least switch the two bugs around as Pinsir has slightly more DPS than Scizor.

I'm not really sure what you did.

I've only attempted Tangela once, so far, and it was weather boosted with Solar Beam.

Did not dodge and used Scizor, Moltres, Pinsir, Flareon, and BB Charizard. Finished with like 50 seconds left.

Perhaps you had too much dodging?

More fire I guess. Just did a Tangela with this team. All level 30.5. 6 seconds left if I remember correctly.

I barely lost with 1 Moltres, 3 BB Charizards, a Fly-quaza, and a Gengar anchoring vs Sludge Bomb Tangela. I messed up and used a Shadow Ball Gengar instead of Sludge Bomb
