Scry is pretty great

Harsh Scrutiny: "Target opponent" So what you're trying to do with that card does not work.
Alternative choices include Funeral Charm as the 1st and best choice due to it's versatility. After that any of the following would work in place. Encroach, Cry of Contrition, Blackmail, Cabal Therapy, Horrifying Revelation, Skull Fracture,

I think I would cut Bontu's Last Reckoning, 2 Yahenni's Expertise for 2 Torment Hailfire and 1 Duress maindeck. In the SB I would cut both Midnight Entourage for 2 more Duress.

After some thought I may add 1 copy of Flaying Tendrils or Drown in Sorrow. I haven't figured out which is more beneficial yet. the exile effect or the scry. I'm leaning towards the exile effect to prevent delve, reanimation or other graveyard shenanigans. Any thoughts on the subject?

This deck needs a Lot of work to be playable. If you want advise I will try to help.

This is not standard legal.
Ob, Nixilis, Gasp of Darkness, Erebos's Titan and Blighted Fen have all rotated out of standard. The Titan for some time now

Thanks for the like. I think having access to Damnation for my sweeper is all I need.

I had actually considered Lightning Greaves. If it gave hexproof instead of shroud I would have made room for it. My inspiration to come back to this deck was Imp's Mischief and I'm unable to target Obliterator if it's equipped with the Greaves. I may very well be wrong and it may be worth testing with tho.

As always all comments and suggestions are welcome.

As well in all honesty I don't think red is needed. Especially considering your mana base isn't running Fetch and Shock lands.
I think it would be much stronger and versatile if you cut Dreadbore for Fatal Push and Crackling Doom for Path to Exile.
Then you could cut Blood Knight for Stromgald Crusader, Knight of Glory, Knight of Infamy or some combination of the 3.
Again just my opinions.

I wanted Dash Hopes to work so much and tried everything to make it good. Sadly I have to say it is not. It falls prey to most punishment cards, giving your opponent a choice is generally a bad thing.
If your budget allows I'd suggest replacing with 3 Swords. Sword of Fire and Ice, would give you some much needed card draw, Sword of Light and Shadow would give some nice life gain and pseudo recursion. After all you're already playing the best creature to equip, Mirran Crusader. Remember double strike also doubles up sword triggers. Dirty business this is.

Just my Opinions, Happy Casting.

What do you think of 1 or 2 copies of Pyromancer's Swath. I think it could work very well with Ensnaring Bridge. Anger of the God's would deal 5. This came to mind since the main issue I've seen come from playing Ensnaring Bridge in any deck other then 8 Rack is that most decks especially control decks can't empty their hand fast enough.

Love it. I've always been a big fan of Sissay and had the same idea at time of the rules change, just never got around to it.

For starters I think you're a little light on the lands even with all the mana dorks/rocks you're running. After all you need mana to cast those in the first place. Speaking of rocks I've never been a fan of the Keyrunes or the Cluestones. They're good in budget builds but I feel there's better options. Like where is Sol Ring?! Or are you following the confines of the horrible dual commander ban list? (If you are following that list I fear this deck is way to slow to compete in a format with a lower starting life total).

Two Planeswalkers I think you really should add are Ugin, the Spirit Dragon and Karn Liberated. They're just too good not to play in my opinion. Removal on a stick essentially is where you want to be in a deck like this without very much removal as is anyway.

Just my opinions, Happy Casting.

I prefer Codex Shredder instead of one of your creatures. Artifacts are less likely to be removed, especially in game one.
Altar of the Brood could also help mill your opponent out too.

Been playing this deck for a couple months now and it's becoming a true favourite.

I've always loved this strategy of winning.
I think Hunted Horror would be a better fit then Hissing Miasma. This gives you another 2 mana source that puts 2 creatures into play under opp control.
As Well I think Flickerwisp would be more versatile then Stronghold Discipline.
Just my thoughts.

No just seemed like it wanted to be a standard deck.

Splashing black for 7 spells 4 of which have double black seems like a bad idea to be honest.In my opinion the mana base in standard just isn't able to give you Double W,B and Blue by turn 3. Which is what you want giving you're running Lost Legacy, Disallow and Gideon. I really think the consistency of the straight up U/W build is more then good enough.
Cut all your black cards and add 2 Disallows , 4 Essence Scatters, 1 Search for Azcanta, and 1 Settle the Wreckage . This will actually give you a much better deck.
I do understand why you would want to play the black cards you have. They're some of the strongest in the format. As well I know that Duress and Harsh Scrutiny are solid side board cards. I just think you're stretching your mana base to thin.

Any way just my opinions take it for that.
Happy Casting :)

You are aware this is not standard legal.

Certain Death It's just way to slow
