I was also checking out what I could do to adjust my party and I could use:
Ninetales, Venusaur & Espeon along with
Arcanine with Morning Sun
Togekiss with Morning Sun or Roost
And Hydreigon with Fire Blast
But for legendary Pokemon, Cresselia can learn Moonlight, which will gain huge boost in HP recovering during Sun!
I love anything that is related to Legendary Pokemon and the Pseudo Legendary are just as good. I would make another myself but it was...a suggestion for you since..I don't know, you might be interesting? ;P I'd for sure like to be co-owner however though haha. If you don't I can go ahead and create one myself.
Just curious though, would you consider...
Zoroark, Lucario and/or Volcarona along that line with the PL or no? Read some arguments about it and everything lol
