The team above got me to 1.4K+, so in my mind it's decent, but I am no expert XD so please do rate this team for me, anyone?

I love seeing how far my mega Gengar hackmons set has evolved. first off, instead of baton pass, you may want a move that can hit normal types, like toxic, in case they try to stall you out with an arceus or something. second off, give final gambit to the chansey, it will be able to kill other impostor chanseys that way (max speed is also necessary as many people don't care what nature their chansey has and it will prevent them from doing the same to you. Third off, instead of thrash give kyurem a dragon type move.

Many thanks to your suggestion of using Dragon-type STAB (completely forgot lul) and the suicidal Chansey, but I would prefer my Gengar to stay a dual support/attack role. Many thanks for your comment!
