So here is Offensive Tangela, I know a youtuber who has used this on more than one occassion and it has always looked like a lot of fun to me. The lack of lefties recovery is helped by regenerator while eviolite gives Tangela some great bulk, enabling it to be one of the best tanks in the tier. Sleep powder essentially equals a ko in 5th gen as long as it hits. This can help against various counters. Leaf Storm is a very hard hitting stab that works excellently with regenerator since you will be switching often. Hidden power ice gives you coverage against things like Altaria, Swellow, and opposing Tangela. The last moveslot is fairly open here, giga drain can allow Tangela to stay in on weakened foes and get some recovery going. It also enables Tangela to use a stab if it is the last mon standing on your team. Synthesis is the more defensive version of recovery for Tangela. Lastly stun spore tends to work well with sleep powder as after they fodder something to sleep you can then paralyze the incoming mon.
Felt like playing Nu cuz of this, don't think I used Tangela once in either match...
