I like the 7x6 boards better than the 5x4 boards. The 5x4's are too hard to get good combos on, more likely to screw out out of having useful attacking orbs.

ml, if you're having trouble keeping your HP high enough to keep Izanagi active, then perhaps you should consider subbing in Santa Hera for your leader. (3x always on is better than 3.5x not turned on when you need it.) And consider pairing a different ally leader; green Odin is of limited usefulness and is 100% NOT what you want for a dungeon that needs high spike damage. My Valkyrie is a good choice, or if you're feeling adventurous you might even take my dark Izanami.

EDIT: One last strategy tip: Rainbow teams are usually not a good choice because they can't stack enough damage when the right orbs don't stack and you can't stall effectively at all. Build a team focused on elements that will give you an advantage in the specific dungeon you're going into.
