Given the number of artifacts you are running, Urza, Lord High Artificer might be a good option. Not only does he turn all your artifact creatures into rocks, he provides an outlet for infinite mana that can allow you to win the game.

Given that a whole lot of your deck can be cast with Flash on your opponents' end steps, is there a reason your removal package is fairly light? I feel some more instant-speed removal options might be helpful.

Vedalken Orrery would be a good redundancy in case your commander is taken out of commission.

I think Phyrexian Altar would be a good choice to add.

Hope some of this helps!

Caerwyn, thanks for the upvote and the suggestions!

I too thought Urza, Lord High Artificer would be a great inclusion, but he's too expensive for me to go get right now. If he comes down in price or I find him in a pack, he'll probably go in. Same with Vedalken Orrery .

I think my removal package is ok right now. If it becomes an issue, I'll consider adding some more, but I'm not sure what I'd cut. More playing will sort that out. What I am considering is changing some of the removal spells. I plan to swap one of the wipes for Urza's Ruinous Blast and maybe Disenchant for Generous Gift .

I think I am going to cram Phyrexian Altar into the deck...I just need to figure out where...

Personally, I would dump one (or all) of the group draw effects to make room for Altar. Think of it this way: in 1v1 would you run a card that says "draw one additional card; your opponent draws three"? That's effectively what these cards do in a four-player game - you net one chance to draw the card you need; your collective opponents net three.

I understand your point, but the group-hug aspect of it doesn't bother me all that much. It can also be a political point, showing how I'm helpful to others at the table, letting them draw cards. That, and I like the card draw myself, so I'm not sure I will be cutting much of them.
