[PTQ]

Please help me come up with a sideboard for the following IBC deck. If the last PTQ 2 weeks ago is still a decent indicator of what to expect in my area, then I should see about 1/3 each R/G, U/G/X (either B or W) and various dromar builds.

4 Phyrexian Rager

3 Goblin Trenches
4 Urza's Rage
4 Scorching Lava
4 Vindicate
2 Void

4 Urborg Volcano
4 Cave of Koilos
4 Battlefield Forge
5 Mountains
3 Swamp
4 Plains

Maybe a couple of Ghitu Fire for the mirror or near mirror. It never hurts to be packing more burn, it's so versatile.

Maybe Death Grasp (for playing against R/G, guarenteed your life total will drop emensely in the first three to four turns. Treminate might be good, too.

Plague Spitter is funny against Thornscape Familiars and Blurred Mongoose. But is annoying as hell to Lynx owner's (side your Lynx's out for the spitters).

Dodecapod? You can count on some fool playing Discard .

Don't worry about Domain of any variant, it's dead!

Where's Gizmo, he's the master at helping out with this stuff, he helped me many times!
