Kraken-Forest Troll-Mab-Kraken defense teams...anyone find any good counters?

Amira helps vs Mab. #EndTheMabness

I’ve never had many problems just using the same team, as mentioned a few times already.

Gloom Leaf (Fully traited)
Sekhma (up to Insulated)
Snowy Owl (up to Insulated)
Plague or Dracos 1337 (up to Impervious) 3rd trait is really nice to have.
