A very nice team, certainly better than mine was when I posted it! Great showcase of the somewhat rare slowbro and the doom desire abuse sets on slowbro, supporting an excellent sun core. Can't criticise the sun elements much, especially not the evs! SR should stay on tran to prevent your opponent switching freely, or at least make them to exert themselves to get rid of it.
On slowbro, over t-wave try yawn if legal? It and doom desire may synergise reasonably well, and the added status wouldn't hurt, possibly netting you setup for blaz. Aside from that, I can't really think of anything off the top of my head as this is being typed on my phone.
Can't see anything to fix really otherwise, will take another look when am on a real pc.
