Could they BE more Super? - Carth the Lion (EDH / Commander) [Revision 6]

This is probably the deck I've struggled the most with figuring out its composition, with planeswalkers being quite complex. I ended up making a chart of the various relevant abilities of the planeswalkers. A lot of them have removal built-in (, mostly singel target).as well as token production and card draw (or card selection/advantage). Therefore, the number of spells in those categories are very low. I'm a bit worried that most of my interaction will be sorcery speed, but that might just have to be the deck's weakness Probably should find a place for The Elderspell... Would also prefer to up the number of planeswalkers a bit more as well. The CMC is also pretty high, so I might want to adjust that some, or at least stick in some more ramp or big mana producers. I'll give it a spin first, hope I get to playtest it soon.

I would very much appreciate some input/feedback from players who have experience piloting superfriends decks, or even Carth decks.
