...Rando, I agree with Spiderman on this issue. It's just not appealing nor does it seem balanced, or even original.
FoR, those are amazingly amazing cards. I love Disguised Assasin! Fresh new ideas here...
I'll expand on FoR's amazing idea for a bit:
Imperial Guard (UU)
Creature - Guard
Imperial Guard can only be targeted by rare spells.
Imperial Guard can't be blocked except by rare creatures.
1/2
>>I imagine this Guard to be one of the high class. He really is a snob...
Royal Crown (3)
Legendary Artifact
Spells cost you 1 less to play.
Rare spells cost you 2 less to play.
>>Here's the Crown. It's good for all your spell, and extra good for those Wraths, Winds, Avatars, and Time Warps. I think Royal Crown would especially be great in today's high-costin' rares...Time Strech for example...
Royal Cleric (1WW)
Creature - Cleric
Tap: Prevent the next 1 damage dealt to target creature or player.
Tap: Prevent all damage dealt to target rare creature.
Tap: Prevent all damage dealt to you. Use this ability only if Royal Cleric is enchanted by a rare enchantment.
1/2
>>He's your usual cleric, except he has the power to fully defend the high-class.
Cause of the Casuals (1W)
Enchantment
Creatures you control gain +0/+1.
Common creatures you control gain +1/+1 instead.
>>Maybe better than Crusade in the right deck. Good luck finding that many playable commons in one environment...
