How to implement "no 4 copy limit" cards?

[Alagos]

I am trying to implement the cards from the Theros block prerelease Challenge Decks into Forge, and I believe that I am almost done with what can be done through card scripting, apart from having more than 4 copies of the creature cards like in the prebuilt decks. I looked at the implementations of Relentless Rats and Shadowborn Apostle, but I can't see anything obvious that eliminates the 4 copy limit, is there a way of doing so through scripting or have those cards been hard coded?

Looks like it's hard-coded. I think you should be able to build the decks and play with the decks if you disable deck conformance in the preferences.
