I've got SB69 leaders with passive skills on most of my teams (I think green is the only one I don't) -- as far as I can tell all monsters that are SR or higher have them. The most common is a 30% boost to Soul for same-element bromides.

Edit: Takeminakata team... hmm. Tricky, because you have to deal with two wood-element sub-bosses but the final boss is fire-element. Means you can't just stack tons of water. Stacking fire MIGHT be a good idea. Two possible ideas:

Tyrannos - Shiva - Echidna - Gadius - Phoenix Knight. (Get Phoenix Knight leveled and evolved before the descended dungeon comes up. This team really needs the orb-changer.) Good friend leaders include Tyrannos, R/D Shiva (R/W Shiva is probably not as good, you need the offensive power), and red Odin.

Blue Odin - Muse - Shiva - Tyrannos (he's sub-Water!) - Archangel. Red Odin is the best choice of friend leader. Blue Odin is second-place.
