Animate Dead... then go into Agent of the Grave @ 13.
Sorry, that probably doesn't help at all.
A couple of suggestions per spell level
1: Snowball, shield
2: Scorching ray, glitterdust
3: Haste, bestow curse
4: Dimension door, caustic blood or greater invisibility
Nope. And you'll need reach spellstrike (min level 9) even to use bestow curse with your ranged attack. The two archetypes you've chosen have little synergy.
If all else fails, take the Coven Hex, pick up Animate Dead, and come join the Dark Side... Agent of the Grave awaits. We can always use a good archer.
If you have a favourite Curse that you want to use with Reach Spellstrike you could use the same strategy the regular Magus uses - eg. Magical Lineage on your favourite spell (except you'll be using the Reach Spell Metamagic feat instead of Intensify Spell).
The only downside to this is that it becomes completely obsolete if you do take Reach Spellstrike, so you likely won't see any use out of it unless there's a level 1 Curse you really like (maaybe level 2), and you'll end up spending 1 more feat than you otherwise would.
I suppose there is this way of abusing that archetype combo. Take the flight hex and learn curse of dragonflies. Fly up then cast curse of dragonflies at a target with spell combat (not spellstrike) if it shows signs of wanting to fly after you.
Not a good move if the target has a sniper rifle (or worse a SAM) of their own of course. Also possibly of marginal use if you have a ground-hugging party.
