It seems to me, that your deck has a
rough start.
I would like to make 3 changes to your deck.
Correct me if I am wrong, you want to use
Dispatch to exil a enemy creature right?
However in your early you will not have 3 Artifacts on the field --> so it will just Tap the enemy creature.
I would consider playing 2
Ultimate Price and 2
Go for the Throat (2 of each for flexibility)
You wanna play
Thoughtcast in the early to find your key cards, however again, in your early you dont have many Artifacts on the field.
Thoughtcast would cost too much i think. I would think about
2
Clutch of the Undercity (Transmute -->
Master Transmuter or
Phyrexian Metamorph , or if you need to
Supreme Verdict)
2
Serum VisionsI dont realy see why you play
Ethersworn Adjudicator.
For me it is a turn 5 play it (do nothing else on turn 5), and on turn 6 you can destroy 1 creature (if your opponent have not killed it)
I would suggest playing 2
Hindering Light (I love this card),
or 2
Lingering Souls, they are sticky as fuck and can block alot.
or 2
Ethersworn Shieldmage, these would even work pretty well with
Master Transmuter return the Artifact to your hand, play it again to protect your creatures. in addition you can
flash it in to protect your
Tidehollow Strix on turn 3 (I know not too fast, but maybe fast enough)
Hope it helps
best regards
