Your argument is too selective and convenient. You say rarity has nothing to do with card balance all the way till the end and say, "It is not used as much as it should be because one of the strongest combos with it involves rares."
I also find it funny that anyone should say, "It is not used as much as it should be" about any cards. Really, you think there should be a card that should not be used much? Interesting.
Ahem, but you've misunderstood me. Card strength in PvP leads to balancing. This is usually determined by how often the card is used, but when one of its strongest combos involves rares, this skews the usage. Thus, you need to go to hypothetical strength of the card or usage in an environment where all rares are available. It is a balanced card based on that.
This is about making the card more playable because that leads to "more enjoyment in the game," which is what is important IMO.
Prevention of a metagame with overpowered cards is takes priority over popularity of a certain card.
I find it funny that while we all know this card is almost never used in reality (I haven't run into a single user with this card in the past 3 months including AIs), there aren't more voices about this card. But, then again, if nobody is using it, I guess it makes sense that nobody really cares lol.
Balancing is based on PvP play because that is where the metagame is. With the AI, if a card is unbalanced, it is easy to change how much that card is used. You can't do this in PvP.
Nope. Not by any chance. I'm too good to lose against a deck like that. I win all my games in 5-6 turns on average. My winning ration is 9 wins and 1 loss every 10 games.
So either you -
Play almost all AI and your balancing experience is mostly void
Or, less likely, you are some PvP prodigy despite having no experience in tournaments and leagues
