Just figured out that 1) is defenders of cosmos pack in shop.
thank you very much for the help, but i tried the defenders of the cosmos and found only 1 dimensional card and nothing else, so maybe i there is a somewhere else i can obtain those cards.
while i'm at it i will ask another question, i just obtained the card "the first giantess" and considering the VERY ominous warnings they gave... is there a bad ending tied to this card?
Only other possibilities for obtaining nearly any card is Lilith's shop which sells random cards individually and the blackjack victory booster which supposedly has any card.
Judging from the other comments I read there's apparently a very crashy boss fight tied to that card. Just using it a few times won't trigger the arrival of the fight where you practically can't let the boss take a turn or else the game will crash though. If you intend to use the card more than 4 times/gain 10k height though be prepared for the possibility of being ambushed by the boss then.
