Since there's been a lack of new quests, there hasn't been much to post about. The game is rotating those old quests every 2 weeks, and soon the ancient dragon series will come to a close. My guides should still be applicable AFAIK.
I did see a slew of new cards, many dual elemental, which are supposedly of the new "demon" or "devil" type. Of course most of them are lolis or whatnot, but I wonder how they will be introduced. Probably golden summon only -_-
The old wiki was closed and if you try to go to it you get redirected to a hentai site haha. Fortunately jeweldragon.tk set up another wiki which retains all the really old and somewhat outdated info, but has a more complete card list.
UPDATE April 1, 2014: Spring festival is among us. Starting off with the Burning Scales quest, I got another opportunity at that smexy Flame Queen card. First attempt I spent 2 gems with a Mobel/Sigurd team because of heart trolling at the boss stage. Final attempt I was able to use an ally's new Thunder Queen++ which is ridiculous (max skill iron wall and 500% RCR recovery every round). Stage 1 is definitely the hardest part with that team setup, but a lucky set of chains and the rest is all history. And no April fool's joke here - finally got the queen herself :)
Erinyes + Thunder Queen at max skill is seriously overpowered. You either take no damage for 3 rounds, or take half-damage for 2 rounds. That was before the new ultimate evolution for Thunder Queen too. Seriously, this is overpowered.
