You might wish to set up a Wish madness on the first turn, by making Wish a free spell already researched and easy to cast. It would work much better with an indie nation set just for that purpose, though.

If you are playing in the game, you might do that still, give yourself a few mages to get all the artifacts on turn 2, and send them on turn 3. Since you are the host, you can already chat like there's no tomorrow, so it should be fine. In this case, you should make Wish your national spell (only you can cast it, and it's pre-researched), and switch it back to a level 9 spell costing 100 pearls once you are done with Wishing.

Wish is the only way I see to allow *any* artifact in the game at no cost (another way would be to make the artifacts at level 0 of research, but they would still cost something, and everybody could make them).
