Your deck has a lot of leaks.. 1) What do you do against enemy Creatures??? ( fast red Goblin deck)
2) What do you do if your enemy can't discard any cards and don't keep his cards in his Hand (any deck)
3) any idea against other control decks?
First change I suppose is to remove all mill or all discard cards. I don't see a positiv effect to have both in your deck
2nd change
Liliana's Caress is only good if you force your enemy to draw card which he discards afterwards. Otherwise you should play with
the rack and
Shrieking Affliction.
I hope I helped you <3
