Role Dealer (Su): Beginning at 3rd level, whenever the card caster randomly draws and throws a harrow card matching one axis of his alignment, the card’s critical threat range increases to 19–20. If the card caster draws and throws a harrow card matching his alignment exactly, the attack’s critical multiplier also increases to 3 and the magus gains a +4 bonus on his confirmation roll. This ability replaces the magus arcana gained at 3rd level.
Deadly Dealer: [some stuff...]Harrow cards are treated as masterwork weapons when thrown using this feat, but are still destroyed after they are thrown. A harrow deck can no longer be used as a fortune-telling device after even a single card is thrown.
Lastly, one of the enchantments that a card caster magus can put on a ranged weapon (even a harrow card) is returning.
1. If you throw a returning harrow card at someone, is it destroyed after being thrown, or will it return to you?
2. If I just buy sets of the 6 cards that match my alignment, can I 'randomly' draw them out of my quiver/card box?
3. If I count cards so that I know that I've got a good chance of drawing a good card (for the purposes of Role Dealer) from a half-destroyed deck, can I enchant this 'stub deck' with returning for keeping the deck the way I like it?
(would a PFS DM be driven crazy by my carrying around a 'half-used' or otherwise messed up harrow deck? are there any other harrow powers that depend on drawing from a deck that's not all together?)
