You want Leyline, obv, at start.

The rest is fairly straightforward. Counter, Condemn, Wrath and O-Ring. Luminarch goes off, EOT for tokens.

I think you need more focus, thus moving stuff to the sideboard or losing them completely, like Baneslayer Angel. I'd play Sun Titan over him. Also, you could probably lose an O-Ring and Negate for 2 Cancel, and have Negate and Spell Pierce on your board as well.
