Stuffy Doll + Blasphemous Act copied by Melek would be pretty insane. Needs more Galvanoth too.

also Arcane Melee would work well here, too

cool design, +1 from me. Have you already tried it out in rl? I'd be curious whether defending yourself with all those bolt effects works. Other than that, ever thought of Soothsaying and Chandra, the Firebrand ?

Brainstorm is an excellent card for a melek deck, I've seen a lot of use with it, I also would recommend cards that give you max hand size (Reliquary Tower or Venser's Journal , the journal being nice with life gain), along with Inner Fire to power some spells with X in them. Blatant Thievery is most likely my number one recommendation for any melek deck, you just get a ridiculous amount of value when you copy it. Feel free to check out my melek deck for other suggestions.

How about Strionic Resonator ? This card could make Melek copy instants and sorceries for only two mana!

I highly recommend Brainstorm , Telling Time , Sensei's Divining Top , Mystical Tutor , and Jace, the Mind Sculptor so you can put spells back on top of your library that you need there.

You could try this Card to sort your top of the library Taigam's Scheming
