OK, now to give my opinion on all these cards....
Simmons
3
Artifact
At the beggining of each players upkeep, that player must choose either to skip drawing a card, or not to play spells that turn.
I'm a little concerned about the timing of this card.
Dance of the Chosen
2GG (Probablly 3GG)
Sorcery
Each player searchs his or her library for all legend cards and puts them into play under their control, tapped.
This is really good.
Channel Alter
2
Artifact
When Channel Alter comes into play, choose a color.
Sacrifice a creature you control: Spells cost you 1 and a colored mana of the chosen type less until end of turn.
I think that with all it can do this card should cost 3.
Drainer
5
Artifact
At the end of your turn, destroy all tapped creatures.
This is really good too.
Dead of Night
1B
Sorcery
Creatures you control get +2/+0 until end of turn. Whenver a creature you control deals damage to an opponent, you must discard a card. If you have no cards in hand, lose 2 life instead.
I made changes directly to the card.
Otherwise this is great. Maybe even B.
3GG
Enchantment
When ~this~ comes into play, sacrifice any number of permanents.
3: Target creature gets +X/+X, where X is the number of permanents you sacrficed when ~this~ came into play.
Somehow this doesn't seem too green to me...
Lake Creeper
1UW
Creature - Elemental
Lake Creeper cannot be blocked.
Protection from all colors.
1/3
This is great.
Metal Decoy
3
Artifact
When Metal Decoy comes into play, tap target creature.
As long as Metal Decoy is in play, the tapped creature doesent untap during its controllers upkeep.
I like this. I was also going to say it should be cheaper but then I realized "no, it's an artifact doing something the other colors usually do."
Convert
W
Instant
Target enchantment or artifact becomes your choice of an artifact, or enchantment.
Draw a card.
The only things you should change are to change "enchantment" to "global enchantment" and to write "instead of any other card type" at the end of the first line. That's just to fix any kids turning an Armadillo Cloak into an artifact.
At least I THINK this is what you wanted without the rules difficulties, but we can work on it if it's not.
GumRingPen
1W
Enchantment
When GumRingPen comes into play, search target players library for a card. Show that card to all players, then put it back into the controllers library. Shuffle that library afterwards.
Whenever the named card is being cast, sacrifice GumRingPen and destroy all creatures. They cannot regenerate.
This sounds like an LoTR reference, which sucks because I haven't seen it (although that may be why I'm wrong if I am).
It has that sort of feel though, and is pretty good. I'd recommend WW though.
Coke
1G
Sorcery
Untap three lands.
Draw a card.
Has this been a card yet? I don't think so. Good. Because it seems like the sort of thing that should be one, and it's always good to end up writing a card like that.
Classic
3G
Enchantment
During your upkeep, for each 3 basic lands you control of the same type, you gain 3 life.
So if you have 4 forests how much life do you get? 3, or 12?
We should work on templating this card so no one gets the wrong idea on purpose.
Chad
2GG
Creature - Genie
If ~this~ is the only creature you control, it gains +3/+3, and cannot be the target of spells or abilites.
2/2
This should read "If not, it sucks."
Oh well, a blastoderm without fading is always nice. I think this card is fine.
Staff of Cool
4
Artifact
When Staff of Cool comes into play, draw a card.
If Staff of Cool is the only artifact in play, it gains, "2: Reshuffle target card in a graveyard into its controllers library."
A selective Feldon's Cane with a requirement... nice.
Control Hammer
2R
Instant
Control Hammer deals 3 damage to target creature or player.
2: Shuffle Control Hammer into your library. Play this ability only if Control Hammer is in your graveyard.
...See I think this card is well costed but there might be some people at wizards who think it's a little undercosted in this environment (where people actually print Volcanic Hammer). But screw them
It's fine.
RoboCard
3WW
Instant
As Robocard is being cast, you may search your library for a copy of RoboCard and put it into your graveyard. For each card you put into your graveyard this way, you may destroy target tapped creature.
Destroy target tapped creature.
I really like this card.
Thinner
3B
Enchantment
During your upkeep, search through your library for three cards and put them into your graveyard.
This card should cost a little more than that if it does it every turn. Buried Alive maybe isn't as cheap as it could be, but it's a sorcery, so it happens once, and it works on creatures only, and it's only 1 cheaper.
Macate
3GGG
Enchantment
During your upkeep, you may seach your library for a creature card, and put it into your hand. Shuffle your library afterwards.
This is well costed though.
Toco
1GGG
Creature - Genie
You cannot gain life.
5/5
In this day and age this isn't
too overpowered. It wouldn't hurt to be 5/4 though.
Blaher
1GG
Sorcery
Destroy target creature. Its controller may pay 3 to regenerate that creature.
Interesting take on that... If we worked on the name people wouldn't say "why is this in green?" which would be good, not that there's much of anyone reading this anyway
Dont Use Steroids
2GG
Sorcery
Destroy all enchanted permanents. They cannot regenerate.
That's a great name. Good card too.
Sick
1UU (Maybe 2UU)
Enchantment
Creatures cannot attack the first two turns since they came into play.
This looks interesting... Don't cast it until after you attack though
Dead at Dusk
B
Creature - Zombie
When Dead at Dusk leaves play, search your library for a card and put it into your graveyard. Shuffle your library afterwards.
2/1
Keeping in mind that its leaves play ability can be very good, I suggest BB. Maybe it can be 2/2 though.
Wje
G
Creature - Wje
When Wje leaves play, target opponent searchs your library for a card and puts it into your graveyard. Shuffle your library afterwards.
1: If Wje is in your graveyard, return it to your hand. You may only use this ability three times per turn.
1/2
This card looks good, but I don't know if it would be possible to make sure it only happens three times a turn, or just any number, because that number might reset when it goes from one place to another.
Slomage's being 1G only bothers me because it means few will use his ability instead of a 2/3... They've only just printed GG for 2/3 with no abilities...
Then again they could save his ability until later in the game when a 2/3 isn't so useful...
Then again, decks like Wood or trinity green might get it out and start using it soon...
Hmmm... I'll have to keep thinking about this. Of course you might have too, in which case I don't need to reinvent every reason for whatever cost... (although that was at least a month ago, so you don't need to remember it).
