Ok, here are some random ideas. Balance have to come later, when more cards are created I think.
Burning Wolf
1
2/1
Rage: Have to attack each turn.
Fire Bolt
2
Deals 3 damage to target creature or player.
Defending Golem
3
1/6
If opponent attacks, Defending Golem must be target for attacking. (Not sure how to word this in a good way, hope you'll understand what I mean)
EDIT:
= Red and
= Yellow, if it wasn't obvious.
