Mono Freaks, consistently 1300e?
I very much doubt you use them from 1000-1300e consistently, but I guess that would be my word against yours and I'd hope you'd be honest about it.
I'm not saying they can't be used, but in all my own experience and that of pretty much everyone I speak with about this, Freaks are very rarely seen in the higher tiers. Mono /or/ halves.
And by consistently 1000-1300, I mean using them straight through from the start without switching out to another deck.
