So how about new cards that are Heroes. They would have specific-type pro noun names. Made up purely for this game.
Two ways of doing it;
Add a Hero slot, it would be not just another creature, but a new type of card. You could only have one hero on your field at a time.
or
More like minor heroes, who you could multiple of on the field.
...
Perhaps both major heroes and then creature cards that are minor heroes.
Anyways, it would add some variety to the game AND would be nice to add onto the story of Elements. Hearing about Ajit the Dragon Slayer (just for laughs) in a story would be quite exciting.

Ideally they would be powerful, perhaps some don't do direct damage, but have abilities like "Morale: If you have more health than the opponent, your creatures gain +0/+2" or something.
cool?
