Now, there aren't as many combat tricks on the blowout level of the uncounterable, unrespondable, +5/+5 and shroud variety these days
Because there are no monsters on his field, the opponent could not respond with Bystial Magnamhut , Bystial Druiswurm or Ghost Reaper & Winter Cherries
The only thing that you can safely trade for in bulk are commons/uncommons for decks (Yanma, Magnemite, Phanpy, etc), or average Trainer cards like Switch, Energy Retrieval, etc
As far as cards go though, I havent seen anyone publicly compile a list of all known vintage card releases
deck.): K type Character card with a cost of 3 or less other than [Scarlet] from your hand rested
