What they should do with the ad cards is include the two gaffs needed for 3 card monte.
Are you kidding? These gaff cards come in several decks as it is and I don't even use it. They also come in most gaff decks do they not?
I know a few of the MagicMaker color decks come with them. They opted with each deck to leave out jokers and ads to swap in gaffs color-matched to the deck. There's more recent "reversed" versions of five of the six original decks - no purple reversed back deck yet. Aside from the reverse-color deck back (color on white rather than white on color, meaning faces and backs have different colors) they're identical to the originals.
