If after I'm done attacking my Unicorn opponent with two Utaku Genshi's out, and destroying one of her provinces... can she use Genshi's ability to attack two of my provinces? If the answer is yes, can she also play a Retribution to attack three of my provinces?
I'm thinking the answer is no, because the first reaction (any of the three) create an attack phase - removing the ability of the other cards to use their effects. If I'm wrong, that's fine... I'm just pretty sure that I'm right.
Thanks.
For the Lion!

Each ability is separate. Yes.
