How do you like playing with 4 Foundy?

I really don't like drawing multiples but I always want to have one available when I play a Thopter or Outcast. I play with 3 Outcast, 3 Thopters and 3 Foundy.

I've been on a green splash for some time now for Decay but I think that without W6 in the meta I might go back to straight UB or even experiment with Esper ninjas for some StP and SFM action. An idea that's floating in my mind right now is some sort of Trinket Mage package as a way to cut down on Foundry. Mage can grab Thopter or Foundry and we could play some Engineered Explosives mainboard. Obviously grabing some SB Needle and GY hate isn't bad either!
