Need help modifying my Red/Blue deck!

I built a Red/Blue deck based on Copying sorceries and instants, but I can't get it to work right, here is my deck so far:

Lands 26
- 10 Mountain
- 10 Island
- 4 Izzet Boilworks
- 2 Terramorphic Expanse

Creatures 12
- 4 Echo Mage
- 2 Izzet Guildmage
- 2 Clone
- 2 Renegade Doppleganger
- 1 Roil Elemental
- 1 Obsidian Fireheart

Other 25
- 1 Gather Specimens
- 2 Rite of Replication
- 2 Personel Tutor
- 1 Fireball
- 2 Surreal Memoir
- 2 Stone Rain
- 4 Staggershock
- 4 Reverberate
- 1 First Volley
- 2 Pyromancer Ascension
- 2 Lightning bolt
- 1 Heartstone
- 1 Chandra Ablaze

I play it on MTGO in classic mode, so no maximum card limit, but I want to try to keep it small with nothing too expensive. Someone Please help
