Still tweaking good ol' Izzet.
I do love it =)
If you mean Desecration Demon ... I've played a few of them before and they usually just stay tapped, especially with all the token and aggro decks floating around with the new sets, you're better off without.
That's what I meant in the original description.
As it stands now, I think it's a strong start.
Sideboard is what will make or break it.
I suck at sideboards =(
I'd Mainboard Dissipate
It's probably the best counter in standard right now.
