I wouldn't bother if they're all commons and uncommons. Even some rares and mythics aren't worth anything and it's just better if you have someone that knows the game to go through it for you. To be fair also, if you were gifted 3,000 cards from someone, chances are they are giving you junk since a lot of players end up with a pile of worthless cards after playing for so long.
On a side note, this is the standard section. It's best to post something like this in the general section.
Any suggestions
