After reviewing the card image gallery, I am speculating that gruul will be very underpowered. After looking through all the cards, i saw that the simic is taking up a lot of space in the mono green cards even when they dont have the guild symbol, telling me that the simic may be easily overpowered. My biggest worry is that those "simic" guildless cards are taking away from the gruul who seem to me to be an afterthought. the gruul seem to be reliant on a lot of mana and there is only 2 green or red cards that can help that. As a gruul fan, i am very worried that the prerelease is going to be a bust for them. please share any other percieved imbalances in the new set.
