I personally think Barbaric Sorceress should have its rarity changed from Common to Epic, Not to make it more valuable for dusting or to make it less common to find in standard packs so less people can find it but because I feel like it's effect is unique enough to warrant an epic gem.
I feel like in the past epic gems were given to cards that maybe weren't the most powerful, but the most unique of their respective set/class, a card that stood on it's own and couldn't be substituted (at least until they restrained it a few years later to make it powerful enough to keep up with the current meta). Barbaric sorceress fits the bill for me as it's brand of netural disruption/spell mana cheat is something not seen by the other cards in the Voyage To The Sunken City Set.
Anyways those are just my random thoughts on a card I see in every Mage deck these days used to cheat out an early Drakefire Amulet and summon a Kalecgos and Deathwing the Destroyer (I pray for death but it will not come). Let me know your thoughts!
...Yes. It's been appearing in every mage deck i've played against in the last 2 weeks which is the exact same deck every single time and I do not like it. This seemed easier than just making a straight up hate post. Thank you for engaging with my content.
Card rarity is just a way to make more money through dust, aside from legendary because they are limited to 1 per deck. Rarity used to be used for the "complexity" of a card but that doesn't hold true anymore, the only place it matters is arena drafting (which could be done on a card-by-card basis anyway).
