MTG Salvation

I've been looking to make a standard deck using the Simic guild, and I started thinking about the following:
1.) Is EVOLVE good enough for standard? Is it too slow, and is the dependence of playing creatures too unbalanced?
2.) Why is Zegana sooooo "good" in standard? You need to have high-power creatures on the board, so why would you take the risk of having a six-mana block sitting in your hand?
3.) Will Master Biomancer's price drop anytime soon? I need a playset for a deck and I don't think it will stay at $10 for long... What price do you think it will stabilize around?

Ok... I see your points. Well, I really like this concept.
The main reason, in addition to the keyword, is as previously stated, most cards need an insane amount of mana to activate them. There are going to be a lot of X(mana) cards as well that would otherwise have low casting costs.
Another mechaninc that I forgot to mention is the use of sacrificing lands.
People don't want to give up one of the twentyfour lands in their decks to activate an ability, and I thought that a cool way to work around this was to include a "land" that could be sacrificed to add to this effect.

I guess I could use Rampant Growth, but I feel it's more flavorful in my set to use the land tokens. All colors are going to need ramping, because the majority of the cards in the set require large amounts of mana to play them. There is a keyword ability I'm introducing called landbind, and it triggers if you control X or more (basic land type).
Example:
Landbind-- As long as you control five or more basic Forests, put a 5/5 green Beast token onto the battlefield at the beginning of your upkeep.

I'm also concerned with the interaction with Doubling Season, etc.

I'm working on a new custom set that focuses on monocolored decks and ramping for each of the individual colors. One idea I have regarding this set is the concept of basic land tokens.
For example, casting an instant would put an Island onto the battlefield, etc.
I'm thinking that this effect/concept would be reasonable if used in moderation, but with the possible interaction with past sets and the official sets, I feel it would become way toooo overpowered.
I'm thinking about having 10 cards in a 275-ish card set to be able to produce basic land tokens, all of which will be rare and or mythic rare.
These are the cards I've designed using this concept so far:

I'm thinking then that I should change the name to Tidal Wave.
I want to keep the mana cost there, or else I feel it would be way way way too overpowered.
I'm going to take out immortality completely.
I have tweaked Tidal Wave in my MSE document but haven't posted it yet, so it HAS been changed, but not here on the thread yet.

What do you think of this card? There is a sac ability on it only to have a synergy with black in the next set in the block which will become clearer later.

I would also like to point out that each color will have a specific synergy with another allied color (which of them has yet to be decided.)
This will be represented in this set as two rares and a mythic rare in those color combinations. In the second and third sets in this block, those colors will become more... definite.

That was the point I was trying to make. I wanted to have a specific cycle that was terrible everywhere and possibly playable as the 22-23rd card in limited.
I have no ideas for what other abilities to give the other cards in the cycle though.
I want to keep the black one the way it is, and I like the flavor that the card Immortality gives. What do you think I should do to improve this?
EDIT-- For the time being I have removed all but the blue card from the cycle until they have been reworked. I am also thinking of just scrapping the fifteen-twenty cards I've created so far and simply fill in the blanks using the themes I want to include. Any suggestions?

Thanks for the input... I thought they seemed a little too powerful, and I was trying to play around with mana cost. I really wanted the enchantment cycle to be at common though. I'll see how I can fix this. Also, these aren't the only cards I've created thusfar. These are only the ones I've been able to post yet. I think that these should stay at common based on the level of the other cards in this set.
On another note, I've added the first mythic rare in the set under blue. Check it out!

Hi guys,
I'm in the early stages of development of a brand new custom set. Nothing here is final yet, but I will still post this and will periodically update this. Now, I will be posting new cards here as the development progresses, and will be posting those cards kind of like a spoiler post similar to that of Wizards. Please, feel free to comment or give suggestions on what improvements/advancements you'd like to see in this set!
I have found it necessary to just state some of the themes and their reasonings found in this set:
The blue cards run a sacrifice mechanic that will have something to do with a pseudo-alliance with black in the next set in the block
The black cards will try to lean across the line of blue-black, thus providing card advantage, bouncing, etc.
I have several specifics so far, so these are the basics so far:

Codename-- "Sun"
Official Name-- ?
Cards-- 253
Block-- Set 1/3 in the _____ block

So without further ado, here are the actual cards:

White Cards

Blue Cards

Black cards

Red cards

Green cards

Colorless cards

Thanks! Flevar is fixed, and I'm working on editing the costs for Eligor.
On the other hand, the mechanic name of Carnival is staying in place. I took a firm affinity to that name, and I'm working on a cycle of cards that effect exiling creatures with names like Ferris Wheel, etc.
Added some new cards!

This is the plane of Hexis. Like others, it is a small world, afterall (couldn't resist the urge to print that) Hexis has your usual spread of races; Humans make up the white mana race (no pun intended), Goblins for red, Merfolk for blue, etc.
But Hexis has one major difference from other planes...
For one week each year, demons, zombies and horrors are free to rule the streets. This time, called the Carnival, is held sacred among those creatures. Because of the "priveledge" of being able to walk the surface, the demons and others who emerge follow a lone rule held high above all others, set forth by the planeswalker who watches over Hexis:
Thou shall not harm.
Becaus this sole rule was put into action, the planeswalker (as of yet unnamed) granted the creatures immortality during this week so they could fully "enjoy" (as far as heartless creatures can) the pleasures of the surfaceworld. Thus, they can't die during the Carnival.
But when the evil planeswalker Nicol Bolas casts a spell that overthrows the rulings of the planeswalker, the demons and beasts are compelled to attack. Because the creatures are still granted immortality, they are currnelty invincible, and there is little to nothing the people can do to stop the demons.

Backstory aside, here are the cards and ideas so far.

Ok...
Carnival seems to be a great mechanic to fit in with the storyline of the set I'm working on. The main reason I like this effect is that they can't die, and that is exactly how it fits the storyline.
I could also try something like an "infinite" undying, but there would end up being a drawback that would eventually kill the creature. I'm trying to, simply put, create a way for the creature in question to never be able to truly "die"

OK...
Here I go...
Someone here said that this seems too close to Yugioh... They're right.
I've decided to ditch the idea of Fused.
Instead, I have a new mechanic idea. But in order for this mechanic to make sense, I need to shed some light on the backstory here...
The plane of Hexis is plagued by demons, zombies and other supernal creatures for one week each year. This time, called the Carnival, allows those creatures to live among those on the surface, but with a catch... they can't die during the Carnival.

The mechanic:

Carnival (cost) (When this is put into your graveyard, exile it. You may cast this from exile by paying (cost) in addition to its mana cost.
Not sure how well this will work, or how OP it is. Suggestions welcomed.

OK... Here's what I think I'll change it as:

Fused (creature type) + keyword
Example, for Flying Fish: Fused Fish + flying
Any other suggestions???

I'll also edit the mana costs... They are certainly too high! Thanks guys for pointing that out!!!
