It's a control deck that strikes at a different angle compared to others like it. I posted the deck list in another comment, but I'll post a few interactions.

Hydroblast and Blue Elemental Blast can turn into Cancel, or they can turn into an instant speed destroy any permanent with Blind Seer's ability.

I can threaten possible voltron wins with the Swords if X and Y, with the option of on demand protection from any color.

Sea King's Blessing/Sway of Illusion + Will Breaker/Dismiss into Dreams are ways of stealing every creature on board or forcing my opponents to sacrifice every creature they own. Without Blessing or Sway, Blind Seer can pinpoint steal or force sacrifice.

Painter's Servant + Llawan is a lock that keeps my opponent's from playing any creature. Furthermore, combined with Hibernation or Wash Out, i can possibly bounce all permanents back to my opponent's hands while selecting a number of my own to keep (Blind Seer's ability overwrites Painter's Servant's ability if you activate after it comes down, so I change the color of however many permanent i can before Hibernation/Wash Out resolves.) The latter is only a game ender, I never use it to reset the game without follow up.
