I HATE Commander

Probs not. I just found this deck on Youtube.

what about curse of opulence?

Stone Rain doesn't have the value that the other land destruction cards have and Curse of Opulence would get no real use since people are going to turn on you almost instantly.

sounds like you just dont want help. curse of opulence is incredible in general, especially in this.

........... Or maybe I have tried this deck before and know what I'm doing. That and I got the deck list off somebody with more experience than me.
When I've played this deck, everyone turned on me instantly. Also, you say "add this card" without offering a way to swap out a card. The best way to try and get me to consider your advice rather saying "Use X".
People do not like decks like this and so giving a card that says "spare me, please!" won't get you very far.

While I do appreciate people trying to give their input and help me, there is a certain give and take that occurs. I have considered your card suggestion and I do not see a place for it [at this time], however if I do find reason to add it after further playtesting and consideration, then I might.

alright, how about this. shatterstorm is better than by force. it costs less and only one of the multiples (if any) can be countered by a single counterspell whereas by force can be stopped by a single one.

I feel like you are mixing up shatterstorm with shattering spree because shatterstorm can be countered by a single spell as well. In either case I think by force is slightly better in this particular deck, although both shatterstorm and shattering spree are good.

Shatterstorm does hit everything, but costs 4 mana at all times so if you want to blow up everything that's great. But if you don't have 4 mana you can't use it., so by force lets you hit at least 1 thing at half the cost, and 2 things for 1 less mana, and 3 things fit the same price, albeit a little more flexible because it only requires a single red mana. So if you are wanting to hit more than 3 things shatterstorm is certainly cheaper.

Shattering spree, which can copy itself is certainly a fine spell, and is harder to counter because of replicate. However, it requires something that by force does not: all red mana. So you can only replicate it as many times as you have red mana which, more often than not, isn't all your lands or mana rocks. So you can't get the maximum efficiency from it like you can with by force. So you trade one kind of flexibility for another.

Just my two cents.

oh yeah i mixed up the names. i know both cards

No worries. Shatterstorm sounds more like a replicate or storm spell than shattering spree in my opinion.

I think that the main reason Shattering Spree isn't in here over something like Shatterstorm is actually because you are going to have very little mana overall. This deck does have a lot of land destruction that also hits you, so I believe that Shatterstorm is more for consistency than anything. That said, Shattering Spree does seem like a good card IF you can keep enough mana overall.

Although the artifact hate cars in here is technically always more expensive than shattering spree by 1 for the same number of artifacts destroyed. But it isn't reliant on just red mana I suppose, so... Eh?

so what about my original point? shattering spree > by force.

Shattering spree is cheaper by one at most times yes, but it also requires all red mana. This deck has a lot of red mana, but not all.

So as I said earlier, by force provides one kind of flexibility in being able to maximize all available mana for artifact destruction, and technically can be just as mana efficient if you have ruby amulet out, which doesn't benefit shattering spree at all.

On the other hand, Shattering spree gives the flexibility of dodging singular counter spells.

I like both, and I think both are good, and personal preference on which to use.

I built a deck around this “punish people for playing mtg” concept and it was mardu, so I got to run personal sanctuary. Conceptually, and in practice, it was okay, but I could never win a four player match with it. It turtles great but when it got down to me and one other player my win condition just wasn’t strong enough late game.

But you can use Field of Ruin to take out something that is a very strong land for them. Also, the deck was made before Rivals, so that card wasn't available at the time. Not to mention that cards like Seismic Strike are here for those games where you get mana flooded. While the deck does have the ability to annihilate it's own lands, the focus is more on the opponent's.

Depends on the deck. But between my RTR block Rakdos, Modern Infect, Polymorph Emrakul and this.......
Yes.

Manabarbs, but worse. Not much point having 2 in here as well, since the deck is trying to limit the number of lands on the field.

That's fair, I run a deck with no land destruction but run Burning Earth because in my meta there's LOTS of depenedance on non-basics, and I run VERY few that produce mana.
