If I were playing a deck that has no fast way of winning the game, I would play a Null Rod to nerf the opponents deck.
And Empyrial Archangel in a fish deck with Dark Confidants and Force of Wills is too reckless. And you say Empyrial Archangel is to be placed played via Vial? When Aether Vial reaches 8 counters, it has two meanings. Either you have won the game or lost the game. In this build, I am thinking that you have lost the game when you reach 8 counters.
4 Umezawa's Jitte is too much. Its legendary and you only have 12 creatures (I am not counting Archangel as a creature).
Sorry to be blunt but this deck looks like a poorly constructed fish deck.
Yeah, it's my 1st fish deck, so I kind of expected it to be bad.
