Evil is correct, the bosses attack so hard that all your cards will die in 1 hit, mtm'ed or not, doesn't matter. Unless you have MTM metros, attack is pretty much all that matters here.

That being said keeping the pieces for DE seperate does not give yout he higest attack, Syc is right about this part, the bonuses you get for max level, transcan, all of those combined give you overall better attack damage.
