Cerebro 4 w/ Carnage

Carnage is here for 2 reasons, but he might get removed from the brew. 

• If you miss on Rocket or for some reason can't play Medusa middle (Knowhere or something), you can still make an easy 4 power thing. Plus, carnage is an easy 4 power when he eats a ninja. 
• The more obvious reason, to eat Sabretooth and make it free.

I'm considering Mysterio over Medusa or Cyclops maybe because that adds another reason for Carnage to be here and obviously works with the Cerebro 4 theme as a base card. 

I feel like moon Girl could be sick for the purposes of doubling up on a free 'tooth, or having more cheap options to play on turn 6 after Sera.
