That's pretty awesome, and you should work on getting your favourite Survival creature next so that you can play Art League in the future with your favourite card

.
I'd say Survival is on of my favourite cards, I even played Welder Survival awhile back and I'm sure you saw my thread on here asking if Survival would be possible in Vintage shortly before Orcish Survival and Varolz-Mask Survival became a thing. Assuming that's off the table, if I had to go for a piece of artwork I'd be drawn to probably Workshop, Tinker, or Time Vault, in particular order.
