Painlock

That's one of the bests mulligan if your turn first. If your turn second then we want nethersoul buster 

If your turn first

(1,2,3... turns) 1 Voidwalker, 2 life tap, 3 thrasher, 4 Diseased, 5 floating watcher

If your turn second

1 Voidwalker, 2 coin +thrasher, 3 attack with thrasher then nethersoul buster, Diseased Vulture

Against aggro we want to survive first turns and then relise value from our's Hooked reavers Diseased Vulture or floating watcher and molten giants then comeback from low hp by healbots, spellstones

Against control we want to set our's hp down really fast for making value from Molten Giants and reavers. While we are seting our's hp down we can make Busters and floating watcher.If you play against Big priest you want to keep spirit bomb for Barns and DO NOT upgrade Floating watcher until your next turn. After remove alls you can get back your table really fast by Diseased Vulture
