What you want to do with this deck is very straightforward
These cards are generally reprints of Super and Ultra (and in the English game, normal Rare) cards of the recent sets, within those recent sets (meaning that you can sometimes get an Ultra Rare card and its Ultimate Rare counterpart in the same set)
Anything currently listed at 30%+ above the recent sold average is overpriced
Sometimes the vendor with the best price for a card in pristine condition would not be the best price for minor condition defects
and if you do, destroy all Face-Up monsters your opponent controls whose Level are lower than the targetted monster
