There's a few questionable cards I see:
-Kitesail is not a clock by any means but it is hand disruption and a
human creature for triggers which is nice.
-Yahenni's feels weird. I feel like you would kill more of your own stuff than you'd want. I'd put in a
path to exile instead. Put the board wipe in your sideboard.
-I don't like anguished or
vindicate (especially
vindicate as a sorcery) -> both are too expensive (cmc). Don't wait for your opponent to play something, put in 3
thoughtseize and get it out of their hand before they play it, also look at their hand and plan your moves. I would have
inquisition and/or
thoughtseize in here for sure instead of those. Also both
inquisition and thoughseize are WAY cheaper.
-Seems like you have a ton of creatures, I would put
westvale abbey in there for sure -> alt win con. You can sack tons of creatures to it and get them back next turn with
proclamation of rebirth.
-Kill martyr of the sands and
mother of runes.
-4
Thalia's Lieutenant, that's a sick card. Need 4 of.
-I'm not fond of
Ranger of Eos. If it's a combo deck, sure he's a great tutor but you aren't doing that. I would much rather have
mentor of the meek.
-Maybe find some room for
metallic mimic?
-Overall deck feels kinda on the defensive to me. I wouldn't look so hard at ways to have answers to everything, you'll figure that out with playing it, I would build it more to win and see what answers you need as you play it. I would also do another
angelic overseer, That's your clock.
