Cool deck! But Cultivate is not a judge promo, it was a FNM promo.
And since you're playing Tooth and Nail, maybe you would be interested in Defense of the Heart judge promo.

Also linking Nissa's Pilgrimage for reference.

WTAF?!?!? When did that judge promo DotH come out???? That's amazing! I def don't want it for this deck, but for my enchantress deck Enchantress Oops! All Permanents for sure. Thanks for catching that error on the promo type; of course it's not a judge promo lol, that was a typo from a long time ago.

Did you ever consider Rocket Launcher as a burn spell?

No I haven't as it's an artifact and the idea is to not use artifacts and to achieve the win at instant speed as a surprise. Rocket launcher, being a permanent, advertises what I'm doing, and being a non-foil artifact, doesn't work in any way. Also, this deck just doesn't need more than one burn spell as it can draw a ridiculous number of cards.

is Rishkar's Expertise getting too good stuff to include in your decks?

Rampaging Baloths could combo with Perilous Forays and Stone-Seeder Hierophant to get all your basics

The expertise is just strictly better than Soul's Majesty in a couple ways but if I always replace cards in all my decks with the new copies then a lot of old cards, some of which are nostalgic for me, will never get played anymore.

I'm aware of the combo with baloths and stone-seeder but for some reason I've never liked baloths so I don't run it in any decks. Thanks for the suggestion though, it is a good one.

Deserted Temple is always worth a spot.

Damn! I'm glad I won't play against this deck with my sliver deck we would be going for ages. I'd have out Sliver Hivelord, Platinum Angel, Crystalline Sliver and the rest of the gang and you would have your WinCon set up. both not able to lose. It would be funny but frustrating as hell. How am I kidding. Five colours vs 1 colour. You would win before I even set up my first combo. Really great deck. Definitely a big fan of the mono green deck.

Thanks its one of my favorites. And Squall Line killsall fliers too so Platinum Angel would die and then you would lose the game for having negative life.

Gotta say, I agree with you completely about Omnath, and also I did NOT expect that combo!

You could probably also add in Hurricane as effectively a second Squall Line.

Thanks for the comment BlueberryPhi. Yeah Hurricane sort of does the same thing but it’s not an instant so it doesn’t really snatch victory from the claws of defeat as they say. Also I don’t think there’s a foil :P

I've played around with this concept before but you have turned this into a work of art! Well done!
