Is it worth getting a second move for Melmetal?
Melmetal, as I've heard seems to be pretty good in Ultra. Flash Cannon hard counters pesky Ice and Fairy types, (Has STAB too) Thunderbolt wipes the floor with Gyarados and Vaporeon seeking non resisted damage, and Rock Slide fares well against the new deity Girantina, and the doubly weak Moltres/Charizard. And to top it all off, Thunder Shock charges these moves "lightning" fast.
However, it's 100 candy, and 100k stardust. Is it really worth getting that second move?

Melmetal's niche is in its role compression thanks to the coverage its charge moves provide. Limiting it to one charge move removes a pretty big aspect of why it's strong. With Meltan candies being easy to farm, you only really have to worry about the stardust cost. I'd have to say that Melmetal's 2nd charge move is absolutely worth it - if you're into pvp.
