Wheel of Sun and Moon (should be pretty easy)
Serum Powder (pretty sure this isn't possible)
EDIT: it looks like
Wheel of Sun and Moon is in the core wad, but it's not showing up in the deck builder. Maybe I need to update...
EDIT: made on Sep 18, added to wad files on Sep 20; maybe the core wad hasn't been updated since then?
EDIT: nope, it looks like the wad was updated on Sep 26 or 27
EDIT: oh right, I hadn't run the sync app...duh
btw: 28/09/2016 1:41:41 AM: Low: Card (NISSA_VITAL_FORCE_CW_417736) in wad DATA_DLC_COMMUNITY_CORE has a FILENAME tag that does not match which will cause problems in-game: NISSA_VITAL_FORCE_417736 (I should probably put this in the community wad thread, hey)EDIT: somebody beat me to it
EDIT: nothing to see here folks, move along
