i dont know if this has been pointed out before, but a poisoned creature will take damage equal to the number of attacks it makes instead of just 1/turn.
an adrenalined frog, for example, will be killed in one turn, while only doing 9 damage.
not sure if this is a bug, or the way its meant to be, but it certaintly puts a dent in the effectiveness of the adrenaline rush farm deck.
