True. I kinda took OP as someone who has studied for some time already but yeah it very much depends on the level of the said learner.
Also, this may be me yelling at kids to get off my lawn, but I think creating your own flashcards is preferable to premade ones for the immediate effect on your memory.
NEVER! You can't make me put in the effort! /s Seriously though I pretty much needed the ready made solutions to get pushed over the edge and I totally get why people might want that. Making your own cards is most likely much better option but that would've taken effort that I couldn't spare myself when I started.
My aim was never to emulate but to play. Blur filters are something that I won't be using.
