Card Caster is....awkward.
One of the things I found was that you can use an alchemist flask for the ranged spellstrike.Which is nifty.
The awkward part of it is that I believe by RAW the spell transfers to the splash damage as well FOR FULL EFFECT and no reflex save for half.
It also says "any touch or RANGED Spell" for its Harrowed spellstrike.
Although, I just place that under poor editing.
Finally, I believe that the player companion product threads actually have the freelance developers commenting on anything awkward about their archetypes. So they might be good for a little bit of context or insight.
