Timeless Set

[Maraxus of Keld]

Okay, I'm gonna break down my comments by category.

Artifacts

I like the Mana Stones. I would actually consider using them in certain decks, especially if I needed just a splash of a certain color.


Black

Balancing Scales is quite nice. I'd definitely use that in my discard deck.

Death Wish might be a little cheap for its ability. I would adjust the casting cost to 1B. Wouldn't be all that different, really.

Depraved Vampire is basically a black counterpart to Warrior Angel. I like it.

Knight of the Stars could be a little better for 3 mana. Maybe add first strike or another ability?

I think Soul Sap is just about right for its casting cost. I can see this in a black anti-creature deck as a way to remove black creatures.

Vampire Hunter can probably be combined with some of those blue cards that adjust creature type to be quite nasty.

Vile Deed is a nice card. It's totally worth 1 life to cycle a hand full of cards that you don't want at the moment, and it can be a fast way to threshold as well.


Blue

I've always liked the concept of Air Conditoner of Rath as a blue counterpart to the Furnace. It has been suggested once that the picture could be Volrath with a beard of icicles.

Gel Elemental isn't too bad of a card. It'd allow you to block a sliver deck with Shifting Sliver in play, for one thing.

Iced Earth - Nice just for the band name. Take that, Cabal Coffers!


Green

Centaur Scouting Party is a decent quick creature. Could fit in a fast creature deck.

Cry of the Land has the potential to be really nasty. Is it just your lands or everybody's lands? I can think of some nasty uses for it either way.

Elder Treefolk makes Treefolk a viable creature type, although I think it would be a little better if he cost one more and also gave Treefolk forestwalk.

Elephant Pack Leader also makes Elephants more viable. I think if he cost one more and also gave all Elephants trample (if they don't already have it) that would be even better.

Fat of the Land is a lot like Vernal Bloom, but not quite the same. Only affecting you is a bonus, plus it doesn't specify just forests, so anything can produce an extra green mana. I shudder to think what you could do with this and a Killer Bees.

Swamp Thing is a lot like Force of Nature, except that he costs two more and is a legend. I think he should probably have swampwalk.

Red

Angry Dragon is a nice playable card. Good midsize creature (flying, I assume), and a bonus Stone Rain when you play him.

Cave In is quite nasty. Red creature destruction, without the limiting factors of equivalent cards in black.

Land Crush would be a great card for a gold deck. Definitely playable.

Mud Slide is a Stone Rain reprint with potential for some funny flavor text.

If this set were actually printed, Plasma Elemental would be a rare. This is a good-sized creature reminiscent of Llanowar Sentinel, but gains points for not being an elf.

Sparks is not quite as good as Shock or Incinerate, but I'd still add them to my direct damage deck.


White

Angelic Favor is one of those cards where you get to smile like an evil bastard right before you play it. Deadly against creature-theme decks.

Blind Guardian is a juiced-up Venerable Monk, but gains points for being named after a good band.

Celestial Annihilation is a great card. Definitely would be one of the rarer cards if this set were printed.

Isara, Angel of War is a pretty nice card, definitely worth sticking into an angel deck.

I would use Oven Mitt just for the name.

Sun's Caress is basically Crusade for more mana, but Crusade is long out of print and it would be worth it in a white weenie deck.

[Volrath, the Fallen]

i like it. the only problem is Death Wish already exists, so you may want to change the name.
