Hi, I come back to this game after more than a year, and realized that I have a Legacy Shadow Claw Gengar, 15IV in attack, but 73% overall. Should I go powering him up, or wait for something better?
EDIT: *PD: I already have more than 10 lucky pokemon, so i think i would not get this new lucky bonus. If there is a possibility of a return of the legacy move, i have plenty of candy to evolve two more gengars, and trading a lot of them could bring a lucky one, so I could add more Shadow Claw Gengars if that happens. Thank you!
Shadow Claw is a legacy move and can no longer be learnt by newly-evolved Gengars. Some speculate that Shadow Claw Gengar may become available again as a Special Research reward (like Body Slam Snorlax) or through a Gastly Community Day.
If your local community is large enough, you should be able to find someone else with another Shadow Claw Gengar to trade with. There is a high chance that both Gengars will become lucky, increasing their IV and decreasing the stardust needed to power them up.
A 73% with 15 attack is great. DO NOT TRADE IT. The chances of it being lucky are good, but it is very possible to get much lower values. I dout there is a lot of difference between your Gengar and a perfect one with shadow claw. A 0/0/0 shadow claw Gengar is better than a perfect one without shadow claw. I have maxed 3 with shadow claw and they are awesome. The best strategy for raids is quick damage and for that these work great. I have also heard there are some Gen 4 legendaries that these will work great for.
Bottom line: Keep it and Max it
Don’t trade it. It already has 15 attack, so the highest damage potential. If you trade it and get a guaranteed lucky you could end up with 12-14 attack (but possibly better defense and stamina).
I’d keep it and power it up. It will be useful for Mewtwo raids, and in gen 4 it will be great for the lake trio, Cresselia, and Giratina raids
