Sea of White Clouds

Can somebody help me build a team? I can't even get past the first one now... Haha it saddens me.

Any suggestions to how to beat this on challenge mode? Did this three times, and died at Leviathan :( I ran several variations of a Horus team, but without a second Horus, the 4x attack doesn't get me through Leviathan.

Thanx to REM pulls as a super-noob (never ever played B4), Ihave a box full of light monsters. Uvo Ganesha, Arcline, 3 Cinderellas, aSprite, FlameChaser, Yellow dragonbowl, 4*knights, and some *junk* I'm trying to decide to feed or sell or build. Yes, I've got every color represented including Christmas Heras (4). Result? With a guard breaker, a sprite, and other orb changers in EVERY COLOR, I can run a light-heavy team with enough other color in sub-element to get through most of things mid-game.

For challenges, I run either light heavy with Ganesha for coin, arcline for power, or DBTyphoon for the XX atk. Add in two duo element sub cast like Archangel for healing and some orb changers based on two main elements in dungeon, and its a struggle to NOT OHKO every level to skill charge for boss. I always choose at least one card that charges skills by a turn or two, and one gravity with additional skill, when possible. I have a friend with a fully awoken Ama, which helped for about 50 levels. Now, even a 3 orb match is devastating. Another friend choice has fully awoken Izanami--that's 5 light orb enhance and 3 dark defense. With all those light orbs it a wash most times.

REM has been bad to me, and I wasted the first 40-odd levels doing it all wrong. My level is far above my knowledge and box contents. Result? Gunghrrrrrgh spites me due to level, cannot farm for early game catches, they will not fall even with weak teams. I have no Sonias, no sirens, no cupids, 1 each Bastet and GrOdin under construction, and am stuck hanging on to evo mat just in case. Still, could be worse, and thanx to PADX for sooo much great info, I can work around it and still have fun.
