My LVL 130 2/1/4 failed on 2 attempts. Leveled him up to LVL 152 and went in with +2 / , +2 / and +2 stockpile.
Saved up 2 , and 3 . Fired off first 2 when I got the AP. When I had 14 collected enough AP for another then fired off , and 2 to finished her off. stockpiled until start of next season.
To make these feel like less of a dice roll they should start avoiding the low cost power characters.
He needs black, but she absorbs that and doesn't need to match it.
Denying 5 yellow is all up to your board.
If you are diligently matching black, even on your best, you will be left with a solo black tile somewhere, aka a loss.
I've gotten close but it doesn't feel challenging it feels tedious, but thats usually clash unless you have them well covered anyhow.
