Sona and blitzcrank bottom lane

Sona and blitzcrank in bottom lane. So a while back I thought of this strategy and used it. Great results actually. Three trials. Two wins, 1 loss. The loss was only because of a first time-Aartrox, blames others, pro-top lane feeder. Welp. Apparently( In my opinion) it worked in the unranked world, how about ranked battles, anyone ever try this? I find it very overpowered... [zombie-brand-mindblown]
