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.
