I'd -1 QP, -1 Momentum and -1 Sanc for +3 Poison in that. Possibly -1 Graboid and another -1 Momentum for +2 Poison too.
PvP1 isn't terribly unprofitable since the electrum reward raise and the fact that you can win any non-Nymph/Mark card, but it will always have lower electrum/hour than AI because of the server delay. Great for fun if you get bored of Bronze though, just like AI4 (which is also very profitable, but more for upgrades than rares) :>
