There barely is a distinction great and good players, to be fair. Most people know how to pill, they just lose games because they are either afking or not playing enough games.
As for your argument of having cyb lhia, why not just bring dolly and muze back then? she is a worse 50/50 than those two. Build a balanced deck? what in your mind does that actually mean? Every clan counters another clan in some way shape or form, there isn't such a thing as a "balanced" deck, but rather it only adheres to metas created by imbalances of power between each card. All's im saying is that playing against Cyb Lhia can be a game lost from the start, since its either "take 7 damage or be down in pills LOL btw u cant reduce me".
Cyn lhia is nothing , very high minimum, you don't know what a balanced deck is? a deck with a damage recucer, soa and sob,
she is a staple vortex card alright but not as dangerous as these cards here http://prntscr.com/6bqeih, and if you think she is godlike then use her in your deck and be happy
Tuck? A threat on par with Sera M1? Didn't know the Tuck's and Raeth's of the world were desirable. Attack manipulation minimum that's above his power and basic 4* stats? I'd take Rico over Tuck and save that * any day.
As for the topic: Cyb Lhia is more powerful than she's given credit for. But every clan counters other specific clans well while they're weak against others. Nature of the game. SOB and SOA and DR come in handy everywhere, which is why you'll always see those decks.
I still believe in the notion that removing powerful low * cards hinders decks more than removing better high * cards (going back to that Lucy debate and now this debate). I'd rather face X-0Dus and Dagg than Cyb Lhia personally.
Of course I'd rather face Lovhak if given the option, but that's just wishful thinking
I would rather face a Vortex half deck of T Gaank X-0dus, Dagg, and C Wing than face a half deck with Cyb Lhia. Unless you're rocking SOA & power manipulation to give you the pill advantage AND stop her poison.
