Crab Warlock spam early.. how to defeat?

[can u chill]

Any tips? Just played game with some that spammed this early, couldn't break them.
Seemed a bit hard to figure out how to kill something with swift and fortified defence AND magic and pierce attack...

Next patch we're nerfing Crab Warlock's synergy with mana (Sacred Steed, Magician, Starcaller). Crab Warlock feels fine on its own, but can be oppressive with additional sources of mana.

In the meantime, tips to beat Crabs:
- Send DPS mercs (especially Pack Leader, Witch, Ogre, Centaur)
- Best waves to send: 4, 6, 7, 10, 13, 14, 16, 18, 20 (especially 16)
- Play them yourself and see how your opponents deal with them
