*Interesting* (I think) Sinnoh Stone/Gen 4 Question

I'll fill the dex, then fill any holes in the lineup

Anything that already has a shiny shouldn't end up getting a special move, as so far all exclusive moves have been released alongside a Shiny.

So Electivire, Togekiss, and Roserade, all look like extremely good picks right now. Magmortar and Honchkrow are also safe, but not as useful.

Rhyhorns are somewhat common here so I won't keep any. But I also have no SD Ttar and no Groudon, so I might need a few Rhyperiors. Magnemite has a shiny now, so community day seems unlikely. Now about Mamoswine... it will get an excellent moveset with Powder Snow and Avalanche. Seriously, getting a good CD move won't make it extremely stronger, Mamoswine will be the top Ice type by far. So will it even get a CD? It would make more sense if Niantic gave Mamoswine a CD with a ground move, but as a ground type it's bound to be outclassed...

Anyway I won't hold back on evolving till I get 3 or 4 Ice Mamoswine for a solid Ice attacking party

I did get a little freaked out about evolving my rhydon, but gamepress makes a good point that if it gets a signature move it'll either be rock or stone, not both - so your old ones will still have value as the *other* type. Nobody is sad to have a double dark tyranitar. I might save my 98% lvl 28, but my other surf rhydons are getting evolved.

Same goes for Mamoswine. Avalanche is already a great move, and Mamo will be a great ice attacker with its double ice moveset - if a CD gives it a great ground move then cool. Magnezone similar - Wild Charge is pretty great as is. Basically if I have a need I'm filling it (save for maybe that one rhydon).

If anything just have one high IV mon ready to go in case word comes down about a CD. by now there has to be over 200 unique evolution lines there is no way every one will get it's own day. Starters are a safe bet. As far as the gen 4 evolutions go look for: shiny release? 3 stages of evolution? Mega evolution?

im personally not evolving my shiny togetic yet, because im paranoid and I dont need a fairy attacker, but i'm probably going to evolve a rhydon because even if it gets a CD, it will only get either a ground or a rock move so it will still be useful ith the opposing moveset.

Thanks to Niantic, my playing style now is only evolve when i need one, and i am satisfied with the movesets.
By that, i mean if i cannot 5 man a legendary, duo T4, or soloing T3 with unique squad non legendary.
So i just evolve a decent one for pokedex entry and let the good one for future use if i need it.

I said F.. all and evolved my 95% lucky Rhydon into Rhyperior. But I feel like you sometimes....all my high IV starters are hostages of future community days....the same with 3 lucky ralts i got from trading. I don't want to evolve them to Gardevoir (or Gallade as soon as it's released) for fear of missing out since they are prime candidates for CD. Luckily Gardevoir is not meta relevant now so it's not too terrible.
The long term effects of giving meta relevant moves inside 3 hour windows is starting to show, meteor mash Metagross being the latest offender to those who missed its CD

I'm only planning for starters. The rest are as good as they can be.
