Plain and simple, we need more crystal allies. Right now purple reigns supreme with flame and sadistue. Yellow is the next best sac with GD but i fear it is really too high cost to play usually and even yellow players tend to go with not-a-rats. If we had more crystal cards, people would consider different routes than just buying sadistues etc. We know that crystal cost is basically free so I don’t see this adding costs to cards. I selected cards that are either generally poor in nature or support cards that need a boost for playability.
And I do not feel like this would make red super powerful or anymore powerful than it is. Most red decks obviously just run flame or sadistue.
So, i suggest a common, uncommon, rare, and epic for each color. I do not see the next expansion adding crystal cards since as it will also be dual color cards, that would be pretty powerful. So lets just add it to the existing cards. I propose:
Blue: Snowblade, Plaster, Cold Mistress, Spirite
Yellow: Non-a-rat, Evil Rug , Crocodime, Green dragon
Purple: Stalagmite, Lava Ooze, Flame, Sadistue
Green: Gerbip, Eelectric, Frock, Squiddiver
Red: Gloat, Twinaxe, Kamicron, War Wraith
These cards should get crystal +1 at level 3 like most other crystal cards. Now, next question would be does something need to be changed to control the number of crystal cards in a deck? I don’t think so. I know people currently running 2 sadistues, 1 flame, and a GD. and I don’t think their deck is any more powerful than others I see. It is true it gives them flexibility as to who to sac but with the above suggestions, I would not be afraid of any deck made up of solely those cards. But I am open to opinions. We could make it so that all crystal allys are unique, and can only run 1 of each in a deck. That would mean if you wanted two sac allys, you would have to run one of the other rarity levels. That would be interesting.
As always, questions, comments, and snide remarks are welcome.
