Coren and I discussed this last night: DC Alterna should be leaps and bounds ahead of Zyrus' LB since Alterna is 5X with ignore 25% SPR and LB is 7.4X max. Personally, I took WoL for 45% DEF/SPR break, two Cids for chaining (mine and friend), Soleil for MAG enhance, and Tilith for overall. Cast DC Alterna, wait an hour (not really), then chain for Alterna to cap. If the first Alterna doesn't take his HP from 90-95% to 0%, quick force close the app and retry the timing. If you are slow, you get locked onto round 2 and eat the Mega Flare and wipe.
Edit: Zyrus has native 50% MAG damage to Dragons so, DracoX2 on him should be 200%.
