HELP AT LV39

[jiangen0801]

This level is really a challenge for me. When enemy summon Squy. His power of one shot is 39. But in next round his power multiplied and one attack can reach nearly 600+ damage! How can I defeat this level like this?!:O_O:

[Knightified]

Bring a hero killer able to kill Squy after the enemy plays him.
