All forest has to do is

triple 0 cost Bayle onto Aether

Play Olivia SE a Bayle
Hit Olivia into the Fox
Hit Bayle into dingdong

Then there is only one ward left over for the Jeanne. So you just have to deal with getting your board cleared by Jeanne who is a 7/8, a 5/9 shield maiden with aura, and maybe a 4/8 Holy Cavalier with Aura.

This is what turn 7 Haven looks like without any of the other new wards.

And the entire goal of this turn is to just stick on the board for Jeanne next turn
