Feels good seeing Pyroak as a menace for the first time. He was always my favourite CAP, being also the time I joined in and I must say I waited for this moment a long time ago. I still remember when I spammed the server demanding a Pyroak revision and how he sucks while the mods telling me to shut up and that it will never going to happen, that he's fine the way he is. Hehe.
Anyway, Pyroak is certainly powerful. I run the standard DD set with Sleep Powder as fourth move but I recently starting to notice this was not doing so well, there was a rise in stall teams. Spikes and SR were hurting badly Pyroak plus with Life Orb his stay on the field was pretty short lived.
I will consider running a rapid spinner to counter this and use a more bulky Pyroak, similair to Bulky DD Gyarados which always did wonders for me.
