I like your deck.
I don't like Serum powder in this deck.
Could be better getting an opt or some potent remouval or sweeper or something for artifacts or some Counter spell to protect your stuff, maybe dive down imo.
I don't think I like it anymore. Removal could work.
Opt is a good card but scrying won't fill up my grave too quickly (in fact, I'm not sure I like
Serum Visions either).
For protection I think a better alternative would be
Clout of the Dominus. It sticks, it's equally cheap, it pumps and it grants haste. Triple-y better, I'd say.

EDIT: Added
Strategic Planning and
Clout of the Dominus.
EDIT2: Went with
Sleight of Hand and
Thought Scour instead!
