Why no Death's Shadow?

Gracco

I'm playing the deck in a more aggressive style which favoured Scourge of the Skyclaves over Death's Shadow entirely but this might be an incorrect decision. Do you have any thoughts on what can be swapped out for it?

Drop the 2 main deck Dismember and 2 Lava Dart is what I think. With only 17 lands, flashing back the lava dart is usually not the play, and it is an objectively worse lightning bolt. Honestly, it is just objectively best to run Death's Shadow. The mana base alone will put in mad work on the life total. Also, in the sideboard, the Inquisition of Kozilek and at least 1 of the Kolaghan's Command should be some number of Thoughtseize. K-Command is only really needed for artifact destruction in this list.

Interesting thoughts, I've found early Lava Darts to facilitate easy kills when gold-fishing but I assume in a game scenario they'd be far less useful. I mainly use Lightning Bolt / Monastery Swiftspear to push their life down and squeeze out a Scourge of the Skyclaves to put on the pressure.

However, I can see how Death's Shadow would be a good draw in the later game, around T3 to T5, to clean things out.

I don't agree with dropping Dismembers mainboard, they prove to be very useful at both dropping my life total and killing threats like Gurmag Angler and Stormwing Entity. Also, more Thoughtseize in the side wouldn't help as I'm already running 4 mainboard. I could replace Inquisition of Kozilek and 1 Kolaghan's Command with Cling to Dust and Spikefield Hazard  ^Flip for Uro cucking.

I did not notice the lone sorcery there. Oops. Uro cucking is reasonable.
