There has got to be something broken we can do with Painter's Servant. We can Muddle for it, as well as Tribute Mage for it, so it would be pretty accessible, though sadly it's not Recruitable.
The obvious combo is Grindstone, but it seems pretty slow and only kills one player at a time.
Yeah the grindstone combo is trash.
The best actually practical thing in EDH Ugin, the Spirit Dragon I think. But I can't think of anything that really has much value with our gameplan.
I'm just glad I don't have to play against any more Paradox Engine - too busy with that to be thinking about brewing
