yea so in my opinion this needs urgent attention.and please build him a side deck.

Honestly, this doesn't look that bad. IT looks like he is going for a Wind powerhouse deck. Tell him to try dropping one Silpheed and one Slate Warrior for two Gyroids. They are wind and can survive an attack.

I think it looks great.
