Cauldron Elemental Card Review
Another bad card. 8 mana for a 7/7 is bad, that’s a start. Giving +2 attack to your Elementals is a very specific kind of buff. Unless you have a full deck built around Elementals, it won’t even affect your whole board. Even in a full deck, if you get some tokens (like Shaman Totems), they still aren’t Elementals, so they won’t be buffed.
To be honest, I’d probably put a Stormwind Champion into my deck before this, and just look at how many people are running Stormwind Champion in their decks.
It can be situationally useful to discover from e.g. Servant of Kalimos if you’re looking for a finisher in your Elemental deck, but I can’t honestly see anyone wanting this in their deck.
Card rating: 2/10
