Franklin, I'm glad you decided to drag yourself out of your smoke-filled room to finally post the deck.
Library doesn't make the list because it doesn't help cast gifts ungiven, yawgmoth's will, flames fusillade etc.
While Library doesn't
accelerate casting any of the above, it does produce mana, so technically it will help cast them. I still say Library is essential in winning the mirror. Although intelligent play and patience may make it unnecessary.
What is the average turn you go off with this version?
Is 2 Gifts Ungiven enough? Do you ever feel like anything else should be Gifts?
Seems like Null Rod + Chalice 0 would really hurt this deck. Although Kowal won w/o any main deck bounce in NY. Have you tested vs decks with Null Rod/ Needle?
I really like the Burning Wish plan. I imagine Echoing Ruin will be an auto-inclusion in the Board.
While LoA is indeed a house, it's just a bit ineffective in this deck. All VAG Gifts wants to do is combo out now, and it really wants the black mana to cast your tutors and Will, and eventually Tendrils. You want to kill so fast that the one or two cards that you might be able to draw off Library is completely moot. It's much more beneficial to drop a Sea/Volc/Island and cast busted blue spells, that will draw you far more cards.
2 Gifts is defeinetely sufficient. Generally, if you resolve it once, you win. There's not really a need to clutter the deck up with more Force of Will fodder.
While Null Rod and Chalice 0 aren't at all very friendly to the deck, there are plenty of ways around them. For one, the maindeck E.Truth + Rebuild are a little bit of a house, along with infy tutors to get them. B.Wish gets Echoing Ruin. If all else fails, there's still two 1 mana artifacts that can be Tinkered into a Fat Guy.
I'd think about dropping the Sea's down to 3 for a LOA. I have never seen a Tendrils Casted off Lands unless it was mainboard you gifts for the will which involves Black lotus which gets you double black and grabbing Jet gives yo ua second black when needed.
It's not necessarily just the black mana that's important. It's the blue / getting to double blue. Colorless mana doesn't cast Recall or Mana Drain, and LoA can't be Gushed back to your hand. On top of that, you want to be playing your spells, not holding them all back in your hand to keep your LoA active.
On an unrelated note, I think we scared off the Colorado guys... I was really looking forward to out-partying them too... Oh well, I guess it's for the better. We wouldn't want to hurt em too bad

Anand, you totally need to come out to MI and get wrecked with me, Brian, and Franklin.
