I can also confirm that this deck is amazingly strong. I am far from a great player and got back into Vintage mainly due to Rich Shay's/LSV's twitch and the VSL. I have gone at least 2-2 in every MTGO event I have played (roughly 20) and 3-1/4-0 more than my fair share of the time with this deck.
It is worth mentioning that in the past I used 3 or 4 Preordain and changed to be closer to this build recently with no problems. I was surprised that the deck stayed somewhat consistent, but trading Preordain for more business/Jace seems to not be such a bad idea.
As I currently see it, this deck has problems with Thing in the Ice and Eldrazi. I imagine adding up to 4 Swords in the 75 should help with this issue. That is likely what I will try in my next event.
Well done, Rich! I have been playing this deck a decent amount (I watch all Rich's streams) and I have had great success with the deck as well. I made top 8 of this same power 9 event with the same deck with a few changed sideboard cards. Rich beat me in the 4-1 round that got him in the top 8 and I got in on tiebreakers. My others losses were both to white Eldrazi.
The deck seems to have great matchups versus all other expected decks. Creatures plus mana denial seem to give this deck a lot of trouble, but that makes sense because the deck is tuned to beat combo, not creatures.
Thanks for all the great work!
