Here are a few of my preferences for this round.
Royalty: Make some really interesting trap. I don't want to see any beartraps or anything. I'd also like to encourage you not to produce art for this card, although there's no rule against it (the rule against this only applies to Enchanter). This is just to level the playing field.
Wizard: Much the same: think of something interesting. The more convoluted and nonsense, the better.
Enchanter: This one is going to be interesting. I want to see a powerful but versatile card, something that could slip into the Dragon's arsenal. I think my votes will be based on versatility.
Bard: I think much of this vote will be based on quality of artwork. Bonus points for stepping out of your comfort zone with regards to artistic style.
Crusader: As many of you know, I'm no expert in PvE in Elements let alone Cygnia. Tell me how your deck works, make it thematic, and that should be enough.
Scribe: Technical accuracy is a must, even if it's all made up. Telling me that Antidragonium melts at a high temperature isn't enough, I want to know the exact temperature and how you measured it. Feel free to go for unconventional "materials", too. Surprise me.
