Hey man I love the deck. Now I saw and I loved the but I wanted instead of turn 1 kills to go for a more consistent turn 2 or 3 kill by adding blue for filtering and counterspells, love to hear what you think.

I think that's a great idea, definitely it's biggest weakness is counter spells / removal and there are a lot of great blue dig spells to help the combo. With the backup of counter spells you could make the combo a lot more consistent.

Maybe we could help the land base? 4 of everything makes me believe you just slapped down 4 because it sounds nice, and I believe that because you only have 4 fetchlands. I'd run 8. It doesn't really matter which color you'd choose (like my deck is mainly red so I go with Wooded Foothills) but since we can fetch for Badlands the life loss for Blood Crypt in mine(modern deck so no Badlands) is irrelevant here.

So whichever fetchland you would like

+1 all the love for Master. Also my deck isn't updated, I'm hoping to finished the rendition I have in paper and bring it to a tournament before updating

I've personally been trying to make this deck for what feels like a year, +1 am making myself

Considering the idea of the deck it's to win on turn 1, wouldn't it be a good idea to drop the number of lands a little? I feel 20 it's too much, if you drop 4 lands you could add Gitaxian Probe to help you dig through the deck, what do you think?

You've got some great card choices here, I especially love Entomb and Shallow Grave. That's freakin' brilliant! I have a deck that is somewhat similar, in that it's all about Master of Cruelties. Please check it out! The Five Finger Death Touch - OF DEATH!

I like the idea of trading lands for Gitaxian Probe to increase the turn 1 win but I've yet to decide on which ones that I would remove because I do find the ability to produce white mana important to deal with leylines, else I would be losing a lot of matches. When I get around to playtesting that I'll let you know.

Also, thanks a bunch!

Thanks for the feedback, I have also had issues against both ExtirpateSurgical Extraction and Swords to Plowshares. Pact of Negation from my sideboard can overcome them and this does make me reconsider putting Thoughtseize back into my sideboard but I would also be interested in hearing any other suggestions to get around those cards.

True, I think I may need to add the Thoughtseize again.

Good point.

I don't fear that one nearly as much as Leyline of the Void which has been a problem.

Yeah, it seems to be a pretty common sideboard card at least it has been on Magic Online because it comes up a lot against the deck.

That is also true, although right now I really do like the idea of not having to switch them from my other deck or shell out the coin to buy another playset :)

Playtested it once and got a t1 win on first try.
