For legal reasons this is not a SW deck (Kozmo budget tempo)

You know what's better than attacking with a monster? Doing that and then sac it to play another monster that can attack and also do the same.
If your opponents make the mistake of letting you go through with our dear Farmer girl, it's GG 9/10 times, fetch whatever you need to ramp up you monster from level 3 to level 8 (you can skip some, don't worry) and look as your opponents' LP deplete to 0 while you still have like 1 or 2 summons and attacks to do.
The archetipe shtick is getting banished whenever you want, so use and abuse that!
A monster is getting removed? Throw it in the shadow realm and bring a spaceship to the field through whatever logic this game has! The evil opponent is making your new beautiful ship explode? Make him regret that by bringing [totally not genderbent darth vader for copyright reasons] or [totally not genderbent darth maul for copyright reasons] to the field and negate his stuff or lock the board because you can and you will.

The extra deck is definitely a thing, not something you really care about so do whatever you want with it.
