Answering the question above: Yes, Nip card was basic, not modified, as the card self has its own restriction to its max potential, therefore adding another conditions to it doesn't have much sense. I am not sure it is something wrong with Nip card in certain, but after playing many cards in my hand plus Nip on a boss, I thought "Wait, am I healed? What happened?". I am not sure, maybe it is just my brain lag, OR I really got a healing effect from something I just played fast without thinking much. Needs to be checked, I may be wrong, sorry.
