Clever Impersonator wont copy non-creatures when played via soul foundry
Step 1: Play Soul Foundry, exiling Clever Impersonator from your hand.
Step 2: Play enchantment, artifact, or planeswalker - You could also just use Soul Foundry itself for this, but this issue exists with other permanent types as well.
Step 3: Use the ability of Soul Foundry to create a token of Clever Impersonator.
Step 4: Choose any non-creature. Clever Impersonator will appear to change into target.
Step 5: Click 'No' - When done with a creature as the target, Clever Impersonator will successfully become a copy of that creature. When done with any other valid target, the copy of clever impersonator will be destroyed.
I had a Clever Impersonator imprinted on a Soul Foundry. I tapped the Soul Foundry, and 4 mana to make a copy of the Clever Impersonator. When the copy of the Clever Impersonator enters the battlefield it targets my Wilderness Reclamation, but then nothing happens. I've had this happen a couple of times.
Yup! Just ran into this issue and thought I was missing something, but no. It should work and it doesn't.
