Need help with SB.

[Esper]

I believe this is where i am supposed to ask for help on Magic deck sideboards. Pretty embarrassing, but i don't know how to 'sideboard'.. Can someone help me on this. I'm running esper control, and my meta at my LGS is mostly aggro, and some U/W Heroic. I need help on what i would actually side in and out against somewhat like aggro decks and slower control/midrange decks.

Drown in sorrow HOSES mono red and glare of heresy is great against heroic

{Ætherspouts} might help as well. Makes Elspeth and other swarmers cry

Yea but the decks that play elspeth don't care if you kill their tokens. There's a good chance they're playing some white control deck as well and they'll find a way to end the game eventually. Plus if they've dropped their elspeth there's probably a counterspell lurking unless it's abzan control.

I don't run aetherspouts, have been thinking about it. But the meta here is mostly aggro, and the deck has been doing well. 4 scorn MB is OP.

Sorry what deck are you running?

Esper control; in the standard thread, I have posted it as 'esper control'.
