The two cards are almost nothing alike.
Eh.. they both use the same exact effect: Rage Potion. Only difference is that Nymph uses it on anyone while this card uses it on itself. I'm not going to start debating on whether or not the abilities are similar because I think everyone can take a look and decide for themselves.
We have Rage Potion. We have Red Nymph. I personally don't see the reason to add the same +5/-5 effect for the 3rd time. But maybe others disagree, I don't know.
Seriously, who uses Red Nymph as an attacker? Especially such an expensive one. It's much better as powerful CC. Berserker cannot be used as CC.
Whether or not it is used is irrelevant. If people are not using it, it's a balancing problem. Making a new card that uses the same mechanics, when we have a 1000 other
unique mechanics we could use, is not the correct fix.
On the element note, Berserker's base stats have very high HP and very low ATK, hence Earth. Its ability trades defense for offense, hence the ability cost is Fire.
Yes, that is true but since it's a built-in mechanic, the creature can be seen as a high attack/low HP rush creature. I think it makes more sense to force earth players to use Rage Potion instead of taking that ability and just adding it to an
card.
Ability cost bothers me a bit too. I've always liked it when Red Nymph ability costs 3
because that's the cost of Rage Potion. It makes sense. But you have the same ability cost only 1
, which is kind of weird. If you wanted to keep that ability, you should consider changing the name to something less aggressive (like "Anger") and make it +3/-3 or +4/-4 . This way smaller cost makes more sense and it differentiates itself a bit from the
cards. It still wouldn't get my vote because it's not unique enough, but it could be a step in the right direction.
