It's definitely a different take on a deck than the one I made. A lot lower of a mana base, and not as much focus on unblockable, but still very cool! I'm not a big fan of Mutiny because they have to have 2 creatures out, and one has to be able to kill the other, and the smaller one has to be the more important one to kill. Meh. I think with Lightning Strike and Magma Spray, you should be fine. I might have to use Magma Spray in my deck. Very good card, especially against the new monsters deck in standard.

I think since you're going for aggro, I'd get rid of Dive Down and focus on getting the kill ASAP. Since you're going for Prowess with Soul-Scar Mage and lots of instants/sorc with Enigma Drake, I suppose I'd switch those out with other instants/sorcs... maybe pump ups or direct damage to player.

If you want your main focus to be unblockable attack, you could always go with something like Simic Sliders 2. In this deck I tried 2 other sub-themes - Enigma Drake as a finisher in an unblockable deck - and 1-drop instants and sorceries that could add an element of control.

2 things - Mutiny doesn't need to kill off an opponent's creature, just make it vulnerable to Magma Spray or Lightning Strike. Dive Down gives 1 of my creatures a 1 turn protection against creature removal, board wipes and attacks. Sure, something like Shock could fill this slot, but I am looking for a resilient balance of aggro and control and want to play as many 1-drops per turn as possible.

Yeah, I need to find some extra card draw for this deck before it will work as I envisioned.

On further consideration, replacing Dive Down with Flood of Recollection makes sense - allowing you to recycle your burn instants.
