WB asuma isn't all that good, because healer team usually have poison, which means despite your shield, you are going to take damage to health. So by turn 2, his buff will be gone no matter what. You will be able to get whatever combo you can on turn 1 but that rarely kills anything.

Also, to use a 60 cost mystery on turn 2, you either have to wait until sage naruto moves (which means enemy gets to do their combo already) or you have to use the earth main to generate that. I think Earth main generate via mystery? Do you plan on doing it on turn 1 to overflow into turn 2?
