[VS] UWR Flash

[conejo]

Ive been having trouble with this matchup. Im playing Air Red now but also have Zs goodstuff laying around. Anyone know what UWR flash players board in/out for us? does it depend on which mono Red deck we are playing? I tried to find a primer for this particular version, but no luck.
heres a list im assuming this is what everyone is playing at my lgs since it has all the cards i saw played against me.

Lands:

4 Hallowed Fountain
4 Glacial Fortress
4 Sacred Foundry
3 Clifftop Retreat
4 Steam Vents
4 Sulfur Falls
1 Island
1 Slayers' Stronghold
1 Moorland Haunt

3 Augur of Bolas
3 Snapcaster Mage
4 Restoration Angel

3 Azorius Charm
4 Think Twice
2 Turn // Burn
2 Supreme Verdict
2 Warleader's Helix
3 Sphinx's Revelation
2 Syncopate
2 Pillar of Flame
2 Counterflux
2 Searing Spear

Sideboard:

2 Pillar of Flame
1 Supreme Verdict
1 Aetherling
2 Thundermaw
Hellkite
2 Negate
2 Celestial Flare
1 Dispel
2 Ratchet Bomb
2 Detention Sphere

Personally I would board out 2 Counterflux, and 4 Think Twice. I would bring in 2 Pillar, 2 DSphere, and 2 Ratchets. Syncopate could be boarded out for Negate in anticipation of Burning Earth. There are already enough Restoration Angels to flash block for value so that not bringing in the additional Verdict seems ok.

As the red deck, bringing in the Burning Earths would be the obvious step. Take out your Pillars and bring in Skullcracks if you have it in your board. Pyreheart Wolf looks attractive in this list since it ignores flashing shenanigans by the Angel. Mutavaults, if you're running it, are good post sweep but seems weaker against this deck that can block it without problems.
