Harpies
Quest. Action: When an opponent draws cards for his quest phase, corrupt this unit to discard 1 card at random from that player's hand if he has 7 or more cards in hand.
Q1. Which is correct?
Case a.
my opponent has 7 cards in hand already, during his quest phase, he is drawing the 8th card, then I could trigger Harpies ability?
Case b.
After drawing cards, my opponent will have 7 or more cards in hand, then I could trigger Harpies ability?
Q2. If case a in Q1 is correct, should I randomly discard opponent's hand card Before or After he draw new cards?
Q3. If case a in Q1 is correct, and I have 3 Harpies in my quest zone, could I trigger all 3 Harpies and randomly discard 3 cards from opponent's hand?
Thank you so much.
