Anki Small Questions Thread - (NO Technical / Troubleshooting Posts)

Hi, I've been a long time lurker and this is my first post on this forum.

so I was wondering how (or if it's actually possible) to filter out cards from my deck of 1000+ japanese words into a smaller filtered deck or custom deck without the cards going back to the original deck after they have been reviewed (which is what is happening now). 

Thanks!
