What ever happened to the notion that if you play well with a well constructed deck, you have a chance of winning. It is never a good thing when one deck defeats anything that does not specifically tech against it. Tech is intended to strengthen a deck against its specific weaknesses, not as a necessity to compete against specific opponents.And you are again missing the point of CCG balance.
You build your deck one way and you take the risk that you will get steamrolled by someone who teched against you specifically. This is the basis of a diverse and challenging game. The important part comes down to your personal skill level to adapt to these uncomfortable (or broken, if you prefer?) situations and how many you can actually overcome of these unfavored mathcups. Pro players get there by dedication and practice.
God save us from a gamestate where we can cover most situations with one set of cards.
By the way, I am speaking theoretically here — I don’t claim Lippy decks have reached that point.
