Basically. When people see something that they are not familiar with it is just human nature to start bashing it mindlessly. You just sorta have to put up with other people doing it. Trying to open up other people's will just cause even more hate. Believe me, I've tried it.
If I were you ,I would definetly ditch an Ametyst Cat for a Cobalt Eagle.600 damage to oponent's life points versus the ability to reuse a pegasus who was caught in a spell binding circle or who is stuck in spell and trap zone,are equaly usefull.
My ex-played more with CB than me,so that's all I can do to help you.GL and HF.
