Mishra's Workshop: possible approach (open to enhancements)

[thefiremind]

I just thought about a possible way to code Mishra's Workshop. It still has some problems, but I hope it can be an inspiration for enhancements and eventually a bug-free version (not necessarily from me ).

What I'm doing here is to decrease the cost of all artifacts that cost or more as long as Mishra's Workshop is untapped. When an artifact that costs or more is cast, Mishra's Workshop is tapped.
This approach still has problems:

• If I have only this land, maybe I want to cast an artifact that costs less than with it.
• With multiple Mishra's Workshops under the same player's control, they would be all tapped no matter what's the cost of the artifact that has been cast.

A possible enhancement could be an invisible token that manages all Mishra's Workshops belonging to a certain player: it decreases the costs according to the number of Workshops and taps only as many Workshops as needed. But then again, if you cast an artifact that costs you probably want to pay with 1 Workshop + any other land, while this approach would always pay it with 2 Workshops.

If anybody comes with a good idea, feel free to experiment.

I attached the new Mishra's Workshop art, used for the MTGO Cube version (much better than the original).
