Let's look at this from an upgrad
ing perspective. Normally, an upgrade is worth 1-2
, meaning that the upgraded form is that much cheaper or has that much better stats. Some cards have more drastic changes when upgraded, but they still are about that much better. (For example, a minor phoenix has lower stats than a phoenix. But a minor phoenix is clearly better than an unupped frog, and about as good as an upped frog. Unupped phoenixes are not similarly superior to unupped creatures around the same cost (nymphs) and are worse than upped cards of around the same cost (AAngel). So we can see that minor phoenix is a more powerful card overall, even if it fills a different enough role that could lead to someone preferring the unupped version).
When lycanthrope is upgraded, its skill cost decreases by 1. Normally, a skill cost decrease would be more valuable than a card cost decrease, since you benefit from that reduction more than once per card. Werewolf, however, only gets to use its skill once. Consequently, the difference from a card cost reduction is that you have more time to generate that extra quanta anyways, and you will not benefit from the upgrade if it is hit with turn 1 CC. Therefore, werewolf's upgrade bonus is worth less than 1
.
Since the benefit from upgrading is so small, either lycanthrope must be OP for an unupped card, werewolf must be UP for an upgraded card, or some combination thereof.
