Your decisions officially have my seal of approval! I just powered up my shadow Tyranitar (89%) to 3876 CP and it's an absolute beast! You won't regret it. Also I am very jealous of that Mewtwo..
I agree, although I would have waited to have enough candy XL and stardust to take the shadow Mewtwo from lvl 40 to lvl 50. A 98% Shadow Mewtwo in Master league classic would be unreal, now it's in pvp limbo
I think you undersold shadow Hariyama a bit, you've got a great one and I find it a pretty good comparable to shadow Machamp - it's not quite as hard-hitting, but it's got better bulk and can be right around the top for counters on quite a few raids.
Metagross and Tyranitar are great choices. Now as for Rock Ttar Shadow since it already has Smack Down good idea to keep it. Now just get yourself a good IV Dark Ttar and you have it covered. I have only powered up one shadow past 40 so far, Mewtwo.
Nice work. I am still less than a year into the game but do currently have 2 level 30 96% Metagross. Plus I've been holding off for now and hoping for Meteor Mash to come back around I have these Metangs: a 98% (for my mega) and 3 shadows: one at 96%, and two at 87% (all with frustration removed).
I love poare ring up my shadows ive been using all my spare dust powering up shadows and have plenty at lvl 40 of different pokemon like metagross, machamp, moltres, raikuo, mewtwos, mamoswines, weaviles all at or near lvl 40
I feel your pain... My first shadows also got purified as I didn't know that in the future wewould be able to TM away frustration. So my 7 15 15 Arcanine has a lovely white glow around it!!
Hopefully Niantic could reverse stardust that already spent in powering up Pokemon. Imagine if Niantic could give us such new feature in the future. In the past, I maxed out 35 fighting pokemon, mostly regular Machamps, to level 40. Now, I do not want to power up so many Shadow Machamps anymore! I am afraid shadow Timbur might come out... After maxing shadow machops!
