I recently received a belated Christmas gift from a friend, a Magic primer/deck.

Creatures[17]:
3x Flametongue Kavu
2x Dominus of Fealty
2x Sphinx of Jwar Isle
3x Stormtide Leviathan
2x Drift of Phantasms
3x Spitebellows
2x Aether Membrane
Spells[21]:
1x Shock
2x Lightning Bolt
4x Izzet Signet
3x Chain Reaction
4x See Beyond
3x Counsel of the Soratami
3x Proteus Staff
1x Steam Blast
Lands[22]:
9x Island
9x Mountain
2x Buried Ruin
2x Kher Keep

This deck revolves around the card Proteus Staff, but is not dependent on it.
This deck is meant to stall with blockers, tokens, and sorceries until mid-game where Proteus Staff and bombs become very potent.
Flametongue Kavu, Lightning Bolt, etc allow for dealing damage to players as well as getting rid of monsters on the field.
Dominus of Fealty stalls, takes control of creatures to do more damage, and plays a good combo with proteus staff.
See Beyond and Counsel of the Soratami fetch out cards and can shuffle bombs and endgame cards back in for potential use of proteus staff.
The Leviathan and Sphinx are for damage dealers and sealing the deal.

This is just the base for my future deck, so are there any suggestions for this deck, which runs on a 20$ budget for improvement? (Taking out Shock for another Lightning Bolt is already considered.)

Thanks!
