@Coinman1863, I'd probably take out the Diabolic Tutors. If not that then Maybe Tendrils of Corruption. In addition the Phyrexian Obliterator would be a great addition in replacement of the Tendrils of Corruption.

Theres a few issues here and i only want to offer you constructive criticism if you intend to use/purchase this deck. Legacy is extremely fast with hard hitting combos. If your deck isn't on fire by turn 2-3 then you may want to reconsider your build. Here's where you will run into serious problems- you have no way to damage your opponent until turn 8-9? Realistically playing against blue control, red, or white, you could expect to struggle. You need (in legacy) to not focus on anything after turn 6, because your deck shouldnt be designed really to do that. I would recommend early creature control in your sideboard- Damnation, Mutilate, Infest, Victim of Night. To be entirely honest i dont see this working. I have a similar deck that i do use, and it is very difficult to beat. Maybe it can offer some ideas (moving away from a large landbase). My Little Lashwrithe

Here is one of my legacy decks if you would like to see what they should be designed to do Torpor Monster Factory

Its_Johnny_Bravo what wrong with the Drown in Sorrows and Toxic Deluges in the board? Aren't the better then all the sweepers you mentioned except maybe for Damnation?

Also how as a Phyrexian Obliterator not hard hitting? It comes out T2-T4.

Coinman1863. yes those are good cards. But this would be a functional modern deck, not legacy. Legacy needs to be absolutely unstoppable around turn 3. I just dont see that here. What's your solution for burn decks? Reanimators? Mill? Control?

Legacy: Make a turn 3-4 win con. I can get a 12/12 out on turn 1.

Nirkana Revenant?

Maybe use some tutors? It'd be a shame if you had tons of mana with nothing to play.

Thanks for all you responses and input.

Mana4ever, good idea but Phyrexian Obliterator is a more potent threat (in legacy) because it costs less and once you play it, no one will swing into it because it makes them loose stuff if it takes damage. The Revenant doesn't instill that fear in the other player.

Grantley91, I agree though I am not sure what to add. Maybe a Beseech the Queen instead of Nantuko Shade as a 1 of?

vittimac, I would have that but Cabal Coffers does the job better because its based on lands, not permanents that could be blown up by other stuff.

Thanks again for all your suggestions.

Just to be safe CanadianShinobi, ThisIsBullshit, xzzane here is my list for the Legacy Tourney. Homebrews for the win!(?)

Magus of the Coffers?

Lotrboom28, not a bad idea but the original land, (Cabal Coffers), is better because its doesn't have summoning sickness. Also Crypt Ghast is better than it because it may not have a good body but everything it has on the card does something as soon as it is played. In short Magus of the Coffers is too slow for this deck.

Looks like you can go a few different routes, such as black Tron style deck(if you want to keep the big mana deal), you could try to do a Griselbrand-Cannon deck with Goryo's Vengeance or you could do a mono-black devotion style deck. What is your play style like?

Are u still trying to make it work ? Nyxathid and focus on discarting untill u can put this and Obliterator on field
