I didn't mean u should take out lands, I meant that u should drop the scry lands for basics and find a way to fit Read the Bones in if u like the scry.

Just play with Hall of Triumph and you'll see for yourself how good it is. Once it's on the board it really has to be stopped or the clock gets real quick. U have 10 1-drop 3/2's. That being said, it's a late game play anyway so fit it in when u can, which is why I advise only running 1.

I'd keep some Brain Maggot on the SB. Like u said, it helps verse control where Despise won't help as much.

Mardu Skullhunter ?

GoblinBushwacker, I'm pretty sure I won't run it. Whilst it is more aggressive than Brain Maggot (the most obvious thing to replace), conditional non-random discard is something I abhor if it isn't in the right deck. However, I will test with him to see how he functions, who knows, maybe he'll be a surprising help!

Crippling Blight is an interesting removal card that hasn't gotten much attention, but I've had some success play testing it in a similar build. It can be good early removal, and later it can remove blockers very cheaply.

Nebulousone, I was thinking about CB, but I've found that Mogis's Marauder and my various fliers are evasion enough to get around blockers. Even if there are many reach creatures or other black creatures do stop flying and intimidate respectively, my other sideboard removal tends to already deal with them reasonably well.
