The question is, the the person drawing the card gain the ability to cast wish (for free) three times, or gain the right to request that the artifact cast wish three times. Because if it's the former, there's no need to worry about monkey's paw syndrome so long as you stick within the safe boundaries of the spell.
If it's the latter, then you need to ask, is this artifact likely to attempt to deliberately screw me over? Is it likely to misinterpret my request from a language or culture barrier? Is it only endowed with a computer-like intellegence?
Asking for wishes from djinn is asking for trouble, because it isn't you casting the spell, and they can twist things for fun, and will try to do so. Wishing for things yourself, using your own power is always safe, unless you get too greedy. Utilizing an artifact? I'm not really sure. It definitely depends on your DM.
