I think you can play Alex, Susanoo, Sneak. Pure 1 block spamming teamBut try to invest in Archon first, he'll get you through alot of the content with no issue.
I think your best team is Maria, Robin, D art riaos. Problem is that in master league alot of Hikaris and Seras which will screw up your initial burst. When that happens I usually buy the start 2 leader block and a 3 block from D'art will finish them off.
Sometimes the AI abit screwed one, I see before Archons dropping a Mana Recycled 3 block even before my Lilith gets her Magic StormA 2 tank set up here is so important I feel.
I no gold to buy the power up in pvp leh LOL
