It's a little bit of a quirky combo but something I just realized in a game on Goko. It requires Fortress and Forge.
Start off buy getting a deck that can draw itself (by trimming with Forge or another trasher or with labs or whatevers available) Get a forge and 2 fortresses.
If its a province game you can Forge 2 fortresses into a province in addition to whatever else your deck can do.
If its a colony game you can forge 2 fortresses and a silver(or some other 3 cost) into a colony. Or you can do the province version to augment points.
I don't suspect its particularly strong, but interesting at least.
