I am going to sleeve this deck up for SCG Baltimore

Although I am still debating about a few cards in my main and my sideboard, here is the list:

Creatures :14
4 deathrites
4 shardless agents
4 tarmogoyfs
2 baleful strixes

instant sorceries : 19
4 Ancestal visions
4 brainstorms
4 abrupt decays
3 FoWs
3 hymns
1 Toxic Deluge

other: 5
3 Liliana
2 Jaces

Lands 22

3 seas
3 wastes
2 bayous
2 trops
4 catacombs
4 mistys
1 Delta
1 Forest
1 Swamp
1 creeping tarpit

Sideboard

1 FoW
3 Thoughtseizes
2 Golgari charms
1 Nihil spell bomb
2 Graftdigger cages
1 Vendillion clique (surgical extraction?)
2 disfigures
1 toxic deluge
2 flusterstorms (1 null rod 1 flusterstorm?)

I was thinking about cutting the Baleful strixes for 1 tombstalker and another FOW in the mainboard. Also How has Clique been performing? I haven't play tested too much combo in my area and if I were to cut it from my Sideboard what should I include instead?
Againsts Combo I have included the 2 flusterstorms- How has flusterstorm performed? I am debating cutting it down to one and playing either a Null Rod or a swan song?

My general siding stragegy for these more difficult matchups is as follows (again, I haven't played much combo in my meta so I need some sideboarding advice)

ANT-

- 1 deluge, -4 shardless agents, -3 AD +2 flusterstorms +3 thought seizes +1 Force, +1 spellbomb +1 Clique

Elves-
