My version of LSV's Mono-blue Engulf control, updated to HOU. Looking for card and sideboard suggestions.

My typical board strategies:

Ramunap Red -> 4x Horribly Awry 3x Authority of the Consuls IN FOR 1x card:Pull from Tommorow 2x Glimmer of Genius 4x Commit / Memory.

GR Midrange/Temur Energy -> 2x Negate IN FOR any combination of Pull from Tomorrow Glimmer of Genius Commit / Memory. Often just don't board at all.

UR Control -> 2x Dispel 4x Negate 2x Sphinx of the Final Word IN FOR 2x Essence Scatter (4x if no Gearhulks) 4x Engulf the Shore 1x Supreme Will or Glimmer of Genius 1x Pull from Tomorrow.

Zombies -> 4x Horribly Awry 2x Sphinx of the Final Word (in case of Dispossess) IN FOR 1x Pull from Tomorrow 3x Commit / Memory 2xGlimmer of Genius.

Will add more if wanted. Add suggestions in comments.
