Zendikar, M11, Akara, This isn't standard.
Right now, there 2 mill decks seem to be Blue Spirits, or Blue/Black Zombies. And if you ain't doing standard. Another good Mill Combo is Spin into Myth /Spell Crumple / any cards that puts a card to the bottom of your opponants deck, then Tunnel Vision your way through their deck.
Right now, if you want to mill, probably the best way would be black/blue zombies, with the mill lands, Undead Alchemist , Sword of Body and Mind etc, as that also gives you an alt win condition (beat down).
thanks guys honestly I get so confused on what kind of deck im playing....I just play on a kitchen table with some guys and drink some beer hahah.....i thought modern was newer cards so I went with standard haha!!
The Tower of Calamities isn't very useful in my opinion. another card:Jace's Archivist and a playset card:Jace's Erasure would help the deck unbelievably. If your trying to make it standard then there is a lot of cards you'd need to remove so i'd keep it modern if i were you.
