Cards like, Bloodsail corsair, rockpool hunter, steward of darkshire, coldlight seer are held even when they're good to play most of the time, and they'd rather use hero power then play these cards. Also with the decks that these cards are in (aggro) it cant afford to lose turn 2 or turn 3 not playing anything. I've reported them and i've tried to write jsons for them as well but i cant get them to work.
