Instant discard

I've been toying with the idea of an instant speed discard deck for a long time, after I first saw Leyline of Anticipation. The idea of discarding at instant speed, to me, is amazing. Just imagine. Opponent draws, instant speed Mind Sludge. So here's my list

Creatures: 4
4x Liliana's Specter

Non-creature spells: 34
3x Liliana Vess
3x Jace Beleren
4x Mind Rot
3x Mind Sludge
4x Liliana's Caress
4x Into the Roil
3x Duress
4x Inquisition of Kozilek
2x Aether Tradewinds
4x Leyline of Anticipation

Lands: 22
4x Drowned Catacomb
7x Island
9x Swamp
2x Terramorphic Expanse

Sideboard: 15
4x Deprive
4x Leyline of the Void
4x Mana Leak
3x Sphinx of Jwar Isle

So this deck obviously relies on Leyline of Anticipation. The fun factor of this instant speed discard is just too much to pass up.

So this deck strategy is to discard your opponent's hand so they can't play stuff (since they have nothing to play), and if they play stuff, you can bounce stuff, and make them discard it.

Then we can slowly build up counters on our planeswalkers, and go for ultimate. If that fails, there is always Liliana's Caress.
