What is the true "Your deck" experience?

What are the worst things that everyone that played your deck has experienced?

As a Chimera player there's two things that define the True Chimera experience:

One is opening an hand that is simultaneously completely unplayable AND contains not even a single handtrap/board breaker. The other is having drawing an hand that can play through just about anything...except the one handtrap they have in hand...

I still love the deck but I'll be damned if it isn't extremely frustrating.
