Shooting Quasar/Synchrons

Here's my Quasar Synchron deck.It'd be much apppreciated if you could help me decide what I should take out of my main deck and side and fill in for what I took out   


EDIT:Also I've been thinking of adding a MST,Should I??

Ofc, u should add MST, for opponent backrow,... duh .-.

The thing is I don't know what to take out for MST

take out a starlight road and mirror forces

Is that the only change I should make to the deck??
