Forum:Tokens and Duel Terminal Cards

So I know there are a few types tokens out in circulation(Double Dude, Sheep, etc) but would it be alright if I took a pic of a token from this wiki (for example, Horseytail) and pasted it onto a worthless(IMO) card? Or would I have to make it myself, for "authenticity"?

Also, if a card is DT, does that mean that when it isn't anymore, does the card have to be replaced or is it still playable if it has the DT design(the glittery dots?
