The Wonderful All-Encompassing Card Clinic

Since it's repeatable graveyard shenangans, the Nomoolus is definitely if not .
For the templating/grammar/typos: At the end of the first ability, you switched the oo with the u.
I'd word the ability ", , Sacrifice a creature: Return target creature card with the same converted mana cost as the sacrificed creature from your graveyard to the battlefield." Since you take a creature from your graveyard, you can leave the "under your control" out.

Nucsiece: Definitely very strong. Can't say if too strong or not.

I invented new kind of card (mine) I don't know if that name already is taken or something and I don't know if it very good or bad.

the mine rules:

1. Mine is a nonpermanent nonspell card and its *not* a land
2. You can have only one mine in your deck
3. When you draw a Mine, put it on the battlefield immediately
4. Mine enters to the battlefield tapped
5. even if a mine has no counters on it, it stays on the battlefield
6. If you search your library for a land type (Forest, for example) you may choose a mine with that type instead (Garden in this case) and put it onto the battlefield

a Semi-Land :

I'm going to make one for fire (a rock) or dark (muddy puddle) and stuff like that

do you like it?

I'm not seeing why this needs to be a new card type and can't just be a special subtype of land. Essentially your mines are lands with depletion counters; they behave like lands in almost every respect. The subtype equivalencies seem very hard to track as well, so much so that you might as well just have your mines have the standard basic land types. Also, you're not just inventing one new card type, you're inventing another in the form of semi-lands.
I'd recommend making your mines a land subtype with a keyword ability like [a href="http://gatherer.wizards.com/Pages/Search/Default.aspx?text=+[Hideaway]"]Hideaway[/a] and have the semi-lands just be land tokens.

mocandragon5 and Flo00 thank you for the feedback, much appreciated!

This is now more of a set based question, is it ok just to have a random 5 color card in a set or is that something that should not really happen?

Could someone tell me if those designs are OP or not and at what rarity should they belong?

Cobblestone Quarry
Land
: Put a charge counter on ~.
: Add for each charge counter on ~.

Blinding Vapor
Instant
Buyback
Target creature gets -2/-0 until end of turn.

Smolder
Sorcery
Erode (Each land you sacrifice while casting this spell pays for .)
Destroy target artifact or land.

Need terrible help with wording and possibly power level. I am currently working on a cycle of five cards that are mythological. They are supposed to be mainly played in a team setting like Battlebond.



This needs help with wording. I might have to choose another aspect for Red. Based on cards that give a choice: Take damage or let me do this un-red thing, like:Molten Influence, Book Burning, Breaking Point and Browbeat


Thanks

Thanks, yeah I was playing with upkeep triggers. It is still too wordy for my liking. I still have not figured out a way to reduce the amount of text but keep the same amount of information. 

It is an incarnation, the last ability is just another play of the incarnation sub-type. The first ones did stuff on the graveyard. The next ones where shuffled from the graveyard into the library. This ones just get shuffled when they leave the battlefield. Might have to decide on something else, though. Comments of other forums discouraged me from having more legendary like supertyes.

The kill mechanic. I mean as you mentioned, not sure how often it will trigger, but having it on the field does affect blocking and trades. Enchantments with, whenever a creature is killed, and the such would have more space and will affect how the other player blocks if he decides to block at all. Though not sure if this is a good thing or not. Dying triggers where not that common at the beginning of Magic, so maybe those types of triggers are common and relevant for a set it is in. Other than that, I do not see it becoming evergreen. Mainly due to how rarely the ability gets printed. In constructed it might give strong creatures pseudo unblockable like menace and the such do. So, it can be relevant but it will be as relevant as those abilities are in constructed.

I'm having difficulty deciding on the phrasing of the main ability on this card I've created. I also wouldn't mind general feedback on it.

Spirit of Rage
Creature - Spirit Avatar
Haste, Trample
Spirit of Rage’s power and toughness are each equal to the amount of combat damage dealt to players during your last combat phase.
Spirit of Rage attacks each turn if able.
*/*

I have an alternative wording for the main ability, albeit a little wordier:
Spirit of Rage's power and toughness are each equal to the amount of combat damage that was dealt to all opponents during your last combat phase.

Neither of the abilities I feel are quite worded correctly, and I wouldn't mind a few suggestions if they seem off to you.

In addition, I have a keyword I'd like general feedback on, as I'm not entirely sure if it's effective at its purpose or not.

Resistant (This can't be sacrificed to pay for costs of abilities or spells you control.)

Its primary purpose in my mind is to put on creatures (or other permanents, but currently creatures) I intend to make for other purposes that ultimately become sacrifice outlets because they have limitations on leaving the battlefield. An example I have made in the past of such a case:

Determination Injection

So, I had the idea of taking the core copy spell mechanic of "Riku of Two Reflections" and the multiple legends with the same name aspect of the forgotten "Brothers Yamazaki" and make a single card that did something interesting in that design space. So, I made this.

Riku from the Seven Mirrors
Legendary Creature -- Illusion Wizard

If you control seven or fewer cards named ~, the legend rule does not apply to them.
~ Power and toughness are both equal to the number of permanents you control which share a name with it plus 1.
Whenever you cast a spell, if you control seven or more legendary permanents, copy that spell. You may choose new targets for the copy.
: Create a token that is a copy of ~.

*+1/*+1

The idea is it'll take a lot of effort to turn it on, especially using just the ability on the card (42 mana). But that cost comes down with clones and other cheap legendaries like legendary lands (dark depths, etc) and legendary one drops and two drops. Then when you do get it turned on, the amount of cheating you did diminishes its effectiveness imagine having one trigger vs having two, then try to imagine seven free copies of your X spell. I know that's potent, but again it'll take a lot to turn it on, and it's super vulnerable to early removal.

The one thing I'm not sure I like is the second clause. I like the idea of him getting bigger as there are more of him, but it makes the textbox crowded. Removing it also gives me room for a snippet of flavor text ("Twins you say?" Count again.).

Thoughts?

To give a cost to lands (that don't enter tapped), you can do things like "When ~ enters the battle field, pay <cost> or sacrifice it."
If you are concerned about haste (so that it can pay it's own cost), you'd hvae to do something like Lotus Vale.
Also, I don't see why this is so expensive. Wall of Stone costs 3 mana, as well as Fyndhorn Elder. So I guess Living Mountain should cost 5 mana at most. Since it also "costs" a land drop, probably less. I'd put it at 3 or 4 mana.
