You're running Island in your main deck, but not Snapcaster Mage , this is a mistake... also, you don't have enough ways to draw cards, it seems, consider some more draw spells, perhaps card:Blue Sun's Zenith? or Think Twice , for value
I'd drop card:Jace's Erasure and 2 of your Increasing Confusion for a playset of Undead Alchemist . Erasure won't be in standard very long, and you don't need that many copies of IC. It's pretty much just going to be a game ender with a flashback cast, so you won't need 4.
I agree that card:Jace's Erasure wasnt that good but Undead Alchemist is a way better fit in a u/b zombie type mill than this one. There is so much removal now and the fact that his toughness is only 2 really makes him kind of crappy in this deck. I would rather put Phantasmal Image in this deck to deal with legends or simply copying Snapcaster Mage . I would really like to try to work in one more Increasing Confusion . best case scenario I can mill someone by turn 6.
Also as far as card draw goes, I would love to add some cards like Think Twice or card:Blue Sun's Zenith but there is really nothing I can think of taking out. In order for a mill deck to work I feel like keeping the opponents creatures and removal countered is the only to make is work. That is why i have no idea what to remove for card draw. I could be totally wrong though.
yeah honestly the only reason why that isn't in here cause i don't own one yet. would love to make some room for it tho.
Ways to react to Elixer = card:Tormod's Crypt which is already in your sb
+1 for the ideas I got for my mill deck Mind Sculpting
against Elixir the good stuff would be the tormoyd's crypt itself
