Oath of Druids

Well everyone, i think its time to give my oath deck one last hurrah before restrictions all but kill this deck. Ive got a good list for my maindeck which i like a lot but i have two major weaknesses: Ichorid and Stax. We will talk sideboard later. Heres my list:

Maindeck:

Artifacts
1 Black Lotus
1 Mox Emerald
1 Mox Jet
1 Mox Pearl
1 Mox Ruby
1 Mox Sapphire

Creatures
2 Tidespout Tyrant

Enchantments
1 Fastbond
4 Oath Of Druids

Instants
1 Ancestral Recall
1 Brain Freeze
4 Brainstorm
1 Chain Of Vapor
1 Flash Of Insight
4 Force Of Will
4 Gush
1 Krosan Reclamation
1 Vampiric Tutor

Sorceries
1 Demonic Tutor
3 Duress
3 Merchant Scroll
4 Ponder
1 Time Walk
1 Yawgmoth's Will

Basic Lands
1 Island

Lands
4 Flooded Strand
4 Forbidden Orchard
1 Polluted Delta
2 Tropical Island
2 Underground Sea
2 Volcanic Island

SIDEBOARD: (UNDER CONSTRUCTION)
4 Leyline of the Void
1 Tendrils of Agony
X Echoing Truth
X Red Element Blast / Guttural Response
X Oxidize / Smash to Smithereens
X Extirpate

Sideboard:
Leyline: the simple, perfect anti flash and dredge card.
Tendrils: another win condition
Echoing Truth: gets rid of those pesky chalices
REB / Guttural Response: good vs flash, forces, anything. deeznauts, etc
Oxidize / Smash to Smithereens: so good vs anything that needs to go away. perfect for Stax games
Extirpate: do i really need to explain?

Im not sure about numbers or what cards for sideboard, but if i run Guttural Response instead of REB i can drop red and therefore drop 2 more maindeck proxies. I really dont know quite what to do for the SB, anybody got ideas of how many or what i should run?

Also, anybody got ideas to make it work post roatation?
