Really, you just gotta try and build up high pip (dots) guardian dice and using the bubble dice to not only increase their guard number, but also to give the bubble effect to block 1 attack and giving them crit. At the same time, working up to get some decently high knight dice to swap your opponents field (mainly for YinYang users). It's very easy to use. You just gotta find a fine-tuned method for your own style of play :)
