I'm planning to test a build with Phantasmal Images with this creature suite (4 Nimble, 4 Delver, 3 Tarmogoyf, and 2 Images). The theory behind this is we can copy opposing TNNs to finish them off. The card can also copy Mongeese and Delvers, and can be pitched to force. The card can be dead if we only have the Image as a lone creature in hand or if there's nothing worthwile to copy.
