Veeerry expensive, but quite probably one of the best Grixis control setups for Modern that I've seen. Well done.

Thanks!

This is one of the first modern decks I've made, and definitely the first I deckcycled.

Price definitely wasn't in mind when I made this buy wow it is very expensive. Like EDH expensive.

Again, thank you :)

I'm not a modern player, so what I did was look through all the cards in modern on Mythicspoiler. Unfortunately that may have skipped cards (Like artifacts)

So are there any cards which I missed?

Control has two aspects which are similar to the stick and carrot thing. i like to call it the stick and bigger stick - control elements and finisher. You are severely lacking the second. Another aspect that is lacking is card advantage. Most of your cards trade 1-for-1 for your opponents' cards leaving both in a similar position.

This deck as it is now is a waste of 1200 dollars (which are highly inflated by the price tags of onslaught fetches).

Start working on those aspects. I will give you a starting point - Delver of Secrets  ^Flip . Here is a sample grixis delver list:

22 lands. Include at least 10 fetches.

4 Delver of Secrets  ^Flip

4 Young Pyromancer

4 Snapcaster Mage

2 Runechanter's Pike - can be replaced with Keranos, God of Storms for lategame power.

12 creatures and 2 wincondtion artifacts that are simply great and cheap threats. 24 cards left to go.

4 Terminate

3 Thoughtseize

4 Serum Visions

4 Lightning Bolt

3 Electrolyze

2 Spell Pierce

3 Mana Leak

2 Treasure Cruise

Most may trade 1-for-1 but those trades clear the way for your aggressive creature suite.

Okay

I find Young Pyromancer to be too slow. I also found Keranos to be too slow. I probably need more card draw, So treasure cruise and serum visions are definitely to be considered. Why run spell pierce when Negate costs 1 more and they can't pay that? Mana leak too, it seems only useful early game. While Electrolyse replaces itself, the damage output seems way too small to justify it.

Because the the early game is the only thing that matters. 1 mana vs 2 is incredibly huge. Electrolyze is good because it draws a card. Dealing damage is just a bonus.

The idea behind the deck is that you want to start with one of the 8 life pressureres in the form of delver and young pyro. They work great in conjunction with all the effects of the spells. With the suite available you are able to answer any threat to you or your finishers.

The key term is tempo - you are answering either a card that with the 2-for-1 of electrolyze or getting early advantages by denying the opponent the deployment of their answers whilst pressuring their lifetotal.

Delver and Young Pyro provide inevitability - they will kill the opponent after a certain number of turns. Everything else is working to help the achieve that.

The alternative to the "slower" cards and additional reason to actually use black is Dark Confidant - it gives you card advantage and threat all rolled into one.

So what would you replace?

Extirpate is too specific. Same goes for Persecute, damnation (if you are going for delver + Pyro + DA), Rift and counterflux are too expensive for what they do, but are decent in the SB. Condescend will not usually be cast for its full potential in the faster environment of Modern and Spell Pierce and Remand are outclassing it. 2-3 lands can also go since you are lowering your mana curve significantly. Additionally, playing one basic of each type is good insurance vs a lot of stuff happening in modern (Fulminator Mage , Path to Exile ).

I realise this is going against the intended control nature and maybe there is a control build that will work, but the above list (that should be taken ONLY as an idea bucket and is far from set in stone) has a more tempo. I myself am curious how Grixis tempo would perform :D

Of course, I forgot to mention - test everything before commiting. The site has a great playtester where you can pit the two builds against each other and see which one feels better to play or anything else that matters to you as a player.

What makes Remand good? you don't technically counter them, just stall them for a turn. The card draw is sweet though.

Condescend is my turn 2 counterspell if need be, if they're tapped out then I can counter their spell and scry 2. Extirpate, like Surgical Extraction is something I see in a lot of decks, and is one of the most played cards in modern according to MTGgoldfish.

I like the idea of my uncounterable counterspell, plus the overload can really ruin combos.

Extirpate can be amazing though, if I Bolt say, Delver of Secrets, then extirpate it, no more of those, or no more vexing devil, lightning bolt, etc.

I find it very surprising that no one mentioned Creeping Tar Pit . it will be the main win condition in your deck. trust me. Im also surprised you aren't running any Snapcaster Mage they are probably the best creatures a control deck could be running. I would also suggest getting as many cryptics in there as you can because they are extremely powerful. This list needs a lot of work, I have a Grixis control deck myself you can look at for some help. Its a great starting point for sure!
