This is a pretty big stretch to look for a drawback.  Try 3 mana sorcery.  Vindicate and pulse don't see play for a reason, they cost a lot of mana at sorcery speed for a card that can only 1 for 1 your opponent

Why not try a drain deck with him and a few Draw 7's?

With him out Timetwister reads Draw 14 cards, Mind Twist your opponent, Reshuffle all graveyards.  Windfall, Wheel of Fortune, same deal.  Heck with him out you can even get value out of things like Winds of Change.

He just seems like a massive beating against control but would need alot of support vs. Shops and Dredge.

Isn't Thada Adel better than this card?

People clearly didn't understand my comparison of draw spells to Manamorphoses.

I would never add an extra color, but taking out 6 cards for Land Grant + Lands seems very intrusive.
This would be acceptable only if it increases your chances of getting the combo out earlier. Testing would have to prove that.

The real question is; what would you take out?
Meadbert indicates he would cut the Chancellors, but that would disintegrate your Ghoul strategy (losing the fat).
I would definitely loose the Chromatic Sphere's before the Chancellors. Also the Memory Jar seems suboptimal, but which other cards need to go too?

IANAL, but there's a difference between making something legal and making something that won't cause legal trouble.  Sure, maybe a judge might find that your program does not infringe on anyone's intellectual property, but would you be willing to fight for that if WotC actually filed suit?  You might want to look over the cease and desist letter sent to magic-league.com recently, which was reposted here on mtgsalvation.  You might also talk to the people who worked on gccg, which was another open source card game player that tried real hard to avoid directly using any of WotC's IP while still letting people play Magic.

The important thing to remember is that WotC wouldn't let you play Magic online with your friends over a webcam if they thought they had any legal chance of stopping you.  Tread carefully, because, as a Mac user who has no viable legal option to play Magic Online, I'd sure love to use your program.

That's not the main point that they have been trying to drive home.  Go read the most recent errata changes.   

The absolute 100% crystal clear goal is restoring functionality.  Given the last year and half of errata, what gave you the impression otherwise (since you say "it seems to me at least")?

@ David:

I think the big difference is that we were fighting a different battle two years ago.   The fight then was to bring Time Vault back to its text.   

Since it is now clear that wizards only cares about functionality, it's a whole new ball game. 

EDIT: "now" incorrectly read "Not" - I fixed my post :p

The engine one is broken with 0 white 0 blue.
