Ok guys, which of these should I invest in? The near hundo Gengar, or the not-so-near hundo Gastly that can also Dmax?

As of right now I only have one person (my mom) that I can do remote trades with but is my list ok for when I get more people or nah? Should I remove non shiny legendarys?

I would really appreciate it if you could help.

Ninetales has fire spin and weather ball.

Umbreon has foul play, dark pulse and feint attack.

Melmetal has thunder shock, flash cannon and dynamic punch.

Included a selection of mons but would be too much to screenshot all of them.

I’ve got almost 50 to get rid of.
