Hey man here are my tips!

1. A color splash should never be under 8 sources, you only have 3... Once your at 8 sources, then why not start playing good cards from white like Utter End, Ojutai's Command etc.? See where I'm going? Take advantage of the splash! You're sacrificing mana efficiency you'd better take advantage of stronger spells!

2. When you play control opponents stack up on dead removal, this is what gives control a strong edge on game 1. Icefall Regent will get removed on sight, trust me. You could put him sideboard and bring him game 2 with Silumgar when your opponent's will have few removal left!

3. What are you planning on exploiting with Sidisi? She doesn't belong in this shell, tapping 5 for a tutor is bad.

4. I've made some arguments about Encase in Ice not being as good as we might think. I invite you to go check them out in the comments from my deck : Esper Dragons. Feel free to get inspired with my card choices too!

5. If you haven't done it yet, go check out Shaheen Soorani's performance in Richmond, link here. Deck list here

Good luck for game day and good brewing ;)

thanks bro def look into it

I'd drop Ojutai's Command and rpelace it with Negate. I'd try to fit another Negate in your SB. It's a great SB card for U/B Control and one they don't leave home without. Crucial in the control mirror.

Negate was in the side and then was taken out. So far from testing even against a control deck I haven't drawn it or necessarily needed it to be honest.
