Surely we will be able to fuck the digimons this time round yeah?

I've been away from the game since Xros set (BT-10 was it?). This new sim, does it have singleplayer mode like Omega or Master Duel?
Also, sold all my cards back then, but wanna play with my friends again. Any recommendation for a fun, non-tryhard deck? Really fancing Kimeramon and Millenniummon.
