Guess "quanta cards" means again "pillars/pendulums/mark cards". I don't really like the term,
for me Immo and Nova are also quanta cards, since they generate quanta. The umbrella term
"pillar-like generators" sounds better to me. That excludes spells (Nova,Immo,Dry Spell), other
permanents (Soul Catcher, Solar Shield etc.) and creatures (RoL etc.)
Which means Nova works as a spell card, so say bye-bye to SoSe decks.
