[Deck] Spanish Inquisition (B/x Storm Combo)

[slave]

I don't understand the usage of Grixis Grimblade at all . Sorry. Why use this card? You can't fetch it and your other MC card is the trow. Please explain
Since my last tournament (I went 4:2, but could not make T8 -.-) I play Skyshroud Cutter > Trow. Saving 1 mana is huge in some plays and I never missed the trow for Chrome Mox

Thanks for the help.
So in regard to Manamorphose - what would you take out for it from my list?

Okay, so Grisix GB is just a thought, not something I know if it works very well as yet.
Grimblade would purely be a target for Chrome Mox.
You know that situation where you're playing a blind D4 with otherwise an empty hand, an LED on the table but no other blue mana, and hoping for a Slithermuse?
Instead of having to crack the LED and taking a punt on the 'muse and calling "blue" when you crack the LED;
I thought having the grimblade would potentially make chrome mox a little more useful, and mean LED sac's would be a little less of a punt.
I realise this isn't the point of having the Trow or Cantor etc. in the deck, so this is just a petty cute idea with no value right?

On another thought, considering the EtW builds that I've read about, are they running a singleton Goblin Bushwhacker as a haste enabler? Should they?

One other thing I'm curious about.
Land Grant.
Do any of you regularly get Dryad Arbor first? I always go for the Bayou unless I need a Culling target to continue.
Is there any other reason to not play pick Bayou first everytime?
