My lvl 30 100% Lucky Drifblim...power up?

super effective against gira and the lake trio and creselia not the best but go for it its tripple resistance on machamp and decent bulk is nice for gym dropping not an extreme cp decay and my 100% (live in the Netherlands) already does great and its only lvl 37 (thats the max i can go right now) so i say go for it. :)

Either way, congrats on the lucky hundo!

It's not the worst dust sink in the world. Low CP decay and triple fighting resistance make it pretty nice for gym defense.

If you've got nothing else to dump 75k dust into then go nuts. Kudos on the hundo lucky.

Unfortunately due to the piece of shit combat system, Machamp spammers can still tap to win without risk of the whole party dying, despite the triple resistance. If you want to use it in raids, forget it, as even Sucker Punch/Dark Pulse Gengar will serve you better.

Not good on offense compared to Gengar, but max it and put it in a gym between the Normal-types. You can then waste attackers' time by forcing them to switch for something else due to triple resistance to Fighting. It also prevents them from just using a 6 Machamp team.
Note: Shadow Ball is not good on defense, TM it if possible, both other moves are better.
