Use sk only after insane 4-10 and put vlad away from pd as he destroys walls that pd needs to stack. You could also drop vlad for gr. Gr will help you 3-flame 2-1 to unlock goblet artifact. Your team should be pd, dd, cp, tg, gr, druid. If you're on android, download this guide. If not on android, the front page has links to yt guides.
