Perhaps you could run 3 Serum Visions instead of Thought Scour? Unless you want your cantrips to be at instant speed, Serum Visions could be much more effective for transforming your Delver of Secrets  ^Flip because it has scry 2. Also, Thoughtseize may perform better than Duress.

Besides for those 2 changes, I think it looks pretty fun.

Thanks BozDaDoz! I am hopefully going to test this soon and see how it will play. I like Serum Visions but the instant speed draw is very effective to gain rapid draw on either turn and it can perhaps soak a counter. Thoughtseize is a maybe. I will try to get them but due to spending a ton on this (Modern is SUPER PRICEY =) ) it may take some time.

Yeah, I hear you. It took me months to get my 2 Thoughtseizes. Another combo that is more funny than it is good in Delver is Ground Rift and Grapeshot with Nivmagus Elemental. He just eats all of the storm copies!

Your in black abuse it!! Tasigur, the Golden Fang is your friend!! He is very easy to delve out especially in a burn deck! He also recycles burn spells or awnsers you may be needing. Since your splashing green Maelstrom Pulse in the sideboard be a very solid card. Id drop the deflecting palms. Their too few match ups where a quick swap on targets will truly matter. Diversity in sideboard is very critical. Maybe have a Treetop Village in your main deck as a 1-2 of because man lands will do you good when your top decking nothing. You could sideboard in Path to Exile agaisnt decks with too many bombs. Your sideboard should diversify your tactics.id take out Smash to Smithereens for them because revelry is a better all around version. It hits more for 1 less damage

Become Immense is the number one reason for green, so why not use it?

I love the list. I would add some Vexing Devils instead of Atarka's Command. I also like the idea of throwing in one Tasigur, the Golden Fang, but I wouldn't suggest to run more than 1 since it's legendary. And one more suggestion, a Grim Lavamancer or two might be nice.

@ BozDaDoz Jamesfurrow and pumpkinwavy. Thanks for responding all!

I like Tasigur and he could be a nice heavy hitter for my colors. Path is probably going to be in the side and Deflecting Palm will have 2 in the side. I like Atarka's Command because it's just better than Skullcrack and now I get to give a pump/burn/no lifegain (adding a land is really unnecessary for me). Tasigur and Grim Lavamancer are relevant late-game handlers.

I like Vexing Devil but command replaced Skullcrack and I need a way to prevent lifegain. Become Immense is a fun card, but not really my main objective. Treetop Village and Maelstrom Pulse are very powerful cards, but I honestly don't need removal over burn, when I am trying to race my opponent for about 4-5 turns.

The reason I suggested those is to help you burn. They will help if u get mana flooded and the pulse is for the mirror match and his varient was faster

If dealing six damage for one card is not your objective in a burn deck, then what is? At least try swapping the Shard Volley, which is just not very good overall, especially if you have to sack your only source of a certain colour, with a Become Immense. I guess it kind of goes against Grim Lavamancer, but it is so much more powerful than lavamancer.

pumpkinwavy the problem with immense is that it's 6/6 that can be completly stopped by a 1/1.... Burn wants more gaurentied cards. A bolt is 3 unless countered by essentially a blue player.

I read Atarka's Command as "Choose one." XD I like it a lot more now.

Ha ha BozDaDoz. I know, you wouldn't see any of them if it was "Choose one".

And Jamesfurrow, this list wants 2-3 land every game, so that's why I have actually 19 land and 12 land with fetching. The removal package is very good, but not what I need :/
