Movesets worth powering up?

DB dragonite would be my first choice of those.

Then maybe SC/SB Gengar, although it doesn't have any ideal matchups he is just a dps monster.

As for Golem you really want RT/SE, but the one you have will do very well too.

Just my opinion...YMMV

I would bring that Dragonite up to 30, you'll love attacking with it if you don't already have a Dragonite attacker.

I would powerup the Dragonite and the Gengar with SC with SB

if i didnt had attackers and need attackers, dont powerup the golem, you want SE with RT, clefa isnt that strong attacker, machamp you want counter and DP, Poli and Pinsir are a no, you can keep them thought using it for prestige

Dragonite is top choice. If you need an attacker for tyranitar (two guys near me also stick them in my gym), your poliwrath would be useful and poliwag candy is easy.

I would power up only Dragonite and Gengar (SC/SB).

• For Golem i'd try to get RT/SE, its a real Snorlax killer and very good for dodging;
• Pinsir better a full bug with stab;
• Machamp you want C/CC or C/DP or even a legacyKC/CC;
• Clefable: not good enough to spend any dust in IMO;
• Poliwrath: I would power up only a RS/DP or B/HP.
