I’ve been having remarkable success this week, even against cookie-cutter meta teams, with this team.
Use Alchemist to feed Valkyrie, and use Valkyrie to feed Tesla. Don’t be hasty with Tesla’s spell; instead, build her armor by playing 4-5 matches whenever possible and use the color transformers to shake up the board and keep the extra turns coming. Don’t be afraid to target red with the transformers, but converting all blue to yellow or vice-versa is a risky move. Carnex is there to be a tanky Impervious in the last slot, another source of armor gain, another Adana troop for a decent kingdom bonus, and another red troop for the extra traitstones this week.
Although the team has no knights, it’s armor-based, it definitely works, and it gets you the event bonus. I’ve only had consistent struggles against teams with lots of spread damage, eg Krystenax/Dragon Soul/Sylvanimora/Elemaugrim or Goblin teams with Nobend Brothers and Queen Grapplepot. Troll/kraken/Mab is hardly more trouble for this team than for my counter-kraken team of troll/kraken/apothecary.
