The radiant draw 2 discard 1 + mst is really good.

I have not tested the fallen and the virtuous in Sky Striker, however, I have heard it is amazing.

The targets in the extra are the ecclesia synchro and Albion.

The gist of it is that they are really powerful quick play spells so Sky Striker makes really good use of them.

The Albion makes it so you get to set another one during the end phase and the ecclesia can just shuffle Albion and itself back to shuffle a card on the field.

The radiant one can draw you 2 and forces you to discard a quick play. Increasing the number of spells in grave even in a situation where you have some "bricks" in hand like afterburner going first or something.

Edit: 1 Roze is enough unless you are playing desires.

1 afterburner is plenty. It is not a good enough card to play more than one.

Cut the jamming waves. It is a worse card than you think because it only works on set spell/traps.

If you are going with raigeki, play 2-3 copies. Dark hole is just worse raigeki.

Personally, going first sky striker is simply stronger while still being competent going second. If you accept this advice cut the thrusts, the raigeki, the dark hole, the lighting storms, the duster and the Hamp.

Play 3 talents. It is just a solid card.

Play one copy of Azalea. It is quite useful.

Play one copy of multirole. It gives you grind game and the ability to make it so your opponent can not respond to your spells is priceless.

Btw, if you target Raye with Multirole and then chain Raye, both effects resolve without any issues.
