The cards on Johnny, Combo Player's Unhinged and Unsanctioned arts are not the same.

On the Unhinged version, from nearest to farthest, there are Soul foundry, Recycle, Clock of Omens, Urza's Contact Lenses, Cadaverous Bloom and Mind over Matter.
On the Unsanctioned version, there are Krark-Clan Ironworks, Genesis Chamber, Myr Retriever, Faithless Looting, Force of Will (to be confirmed) and a unknown (yet) card.
Krark-Clan Ironworks, Genesis Chamber and Myr Retriever were already mentioned in the Unhinged version's flavor text.
