Answer 1

Hm, it JUST JUST JUST makes it to 8/10.

It's a good deck.

Answer 2

The biggest issue I see is your mana base. I know sac lands can be expensive, but there are alternatives. You can play evolving wilds or terramorphic expanse to fetch whatever land you need. Also, the grixis tri-land would do wonders for you. I would eliminate the borderposts and put in 4 of the tri-lands and put in some of the come into play tapped lands found in Zendikar (I forgot their names). Good deck though.

Answer 3

looks fun. it's a bomby deck filled with awesome creatures and control. sounds great for multiplayer

Answer 4

good,go into battle often
