Have you all looked at the list of future evolutions of current pokemon?
There is so much i still need, or can use more of, that every event helps. I will chase magmar, need more of it, because it will get another evolution. Same goes for sneasel and swinub.
Also looking for lapras because it is a most viable arena attacker, also small ones for prestiging, and looking for Houndour, i need a good one for Houndoom.
Building towars a nice collection of gym prestigers is also a good goal, i could still use more double-STAB ice or fire pokemon with the right CP for that.
So if you give me another whole lot of slugma, i will be happy, sort them according to CP and IV, and evolve them into specific target CP windows, hoping for double stone STAB or double fire STAB movesets. Meaning Ember / Overheat or Rock Throw / Stone Edge. Both are top movesets.
Houndoom can also have two top movesets, double dark STAB or double fire STAB.
Double ice STAB is obviously amazing against dragonite.
