If you have JG not fully covered (mine is 3/3/3) deny 
at all cost. if she ever gets
off it is game over.
Start the match with 
and 
stockpiles plus
& 
match boost or rainbow stockpile as the third.
Again denying
is the most important.
If you have some amount of blue covers leaving a match 5 row for moonstone can be beneficial if the 
does not match away. Take care and look how the board would develop.
Gather
and
with second and third priority, try to keep 12
ap & 10
ap stockpiled.
Denying 
should be the fourth priority.
When she gathers enough
use
if you don’t have special tiles so she moves one of your tiles rendering her ability useless. she will use
before using
so firing
before is still save if she has black.
Once she stole tiles with
use
to make them go away.
I made it on the second try, might have been a bit lucky.
