Let's get the ball rolling with the new abilities. My character is from the Holy splinter and is the Silvershield Drummer with drumsin his hands and a flag attached to his back. The drums mighty sound would increase team morale and by that Amplify (1st Ability) the teams. It would have 5 mana and 1 magic damage (as it frightens the enemies), 1 speed, 1 shield and 1 mana. This would be a rare card. With level ups it would get additional health and shield and the second skill it would get is silence making it a great counter against magic teams. Which is understandable, as their noisy behavior distracts the magic wielders. On their highest level they would get 1 additional magic attack, as they have perfected the concentration of sound waves against there enemies.

So in short:
Silvershield Drummer
Rare card
1 Magic Damage
1 Speed
1 Armor
1 Health
Amplify
On level ups it would get mainly shield and armor.
In silver level or higher it would get Silence
On max level it would get +1 Magic Damage
