I would like to put this out there cause it has come up in one of the recent games i have played. The issue is with the cards for Protoss Tassadar group, the cards are Leg enhancements and The hero card Zertul's special ability. The scenario where it came up was i had both these cards in play and i had just played a move order into my friends planets, into an area with a zergling and a ultralisk. I attacked with 2 zealots and Zertul thinking that both the ultralisk and zergling would die and would wont have to face anyone. Which brings up my issue, my friend reads the cards and decides to use zertul's ability on the zergling which canceled out my zealots leg enhancements so the ultralisk lived. which i disagreed with being feeled jipped out of a free space and the uselessness of having both cards in play.
my question is how should it be played out? Considering both say play at the start of a battle and both say the opponent choices which unit dies, we were at a stand still which way it should go. I completely understand both sides of the coin in this situation, where the attack would go with cause it says "must kill" it should follow air/ground splash rules as it kills as many as possible and the Defender sees as his choice which to kill off so choice the least amount of deaths possible to saved the more expensive units. Plus since this new expansion it seems that the game encourages attacking thus attackers are usually favoured thing also came up in the debate.
We ended up playing as in favour of the defender which didnt matter cause my numbers crushed the ultralisk and in the end its a game and battles are more fun then nit picking at every detail, but we still were interested to see what other would think on the subject.
