I dont like the nonland clause but what if this CIPT?  The whole black mage using a tool box idea works with this as its something that would take a bit of time.

Adding a second target further narrows its applications and I just dont see a reason to do it.  I am going to go with the change by a certain amount wording though as it seems more elegant to me.

Fine, Waking Dream.  Other flavor text suggestions?

Choose a number no greater than 10. Target spell's or permanent's converted mana cost is equal to that number until end of turn.


I hate having the "no greater" clause but with artifact mutation (also Rush of Knowledge) this is a pretty strong combo (of course its also 3 colors and 3 cards but still).  In most other cases it's more of a neat trick.  I want the name to have something to do with the target's local energy field and manipulating that.

EDIT: actually if it changed it BY a certain amount that would also be interesting, like:
"Increase or decrease the converted mana cost of target spell or permanent by up to 3 until until end of turn."

Waking Dream is a bit too much like Waking Nightmare although I do like it.  "Dream Passage"?

And playing what is essentially a 6 mana sorcery to kill your arcanis is harder than oxidize how?

It could also be "comes into play under your control".

Remove target creature from the game.  Until end of turn you may return that creature to play under its owner's control any time you could play an instant.  If you do not, return that creature to play under its owner's control at end of turn.


I really like white's various slide spells and thought this would make a nice addition.  Also great with CIP abilities.

Exactly.  Yes it never leaves your hand and that's the point, it's not in play and your hand isn't a public zone anyway.

When permanents leave and re-enter play the game treats them as completely different cards, it doesnt remember the state of the card.  I think this keeps you from using once per turn clauses on these as the game will not remember that card being in your hand.  You could make it a rule part of the reveal keyword-"You may play reveal abilities once each turn" or something.

I think that it has far more relevance than "sacrifice a creature", the hand is typically associated with the mind and magic and an additional tax on those faculties seems quite in flavor to me, Force of Will has a similar drawback that I believe fits it perfectly (and very poorly the other alliances pitch cards).  Forbid has a similar buyback cost so there is some history of this being associated with counterspells.  That said, it is certainly not my first choice but I feel the soft counter alters the flavor of the card even further and 4cc counters tend to be terrible.
Also there were few replies refering to Dandan's fix which I was quite in favor of and would gladly take over the discard if it is useable.

Im changing it to:
Seal Magic

As an additional cost to play Seal Magic, discard a card.
Counter target spell.  Until end of turn spells cost an additional 1 to play for that spell's controller.

Which I feel conveys the great mental/magical effort needed to lock-out the casting of another wizard while maintaining a playable casting cost.  Do you feel this is balanced?

I think "Whenever a land you control would be destroyed, you may sacrifice Consecrated Ground instead." is a better wording.

My thought was this+Hokori. CMC seems easier to balance.

The damage drawback isnt very white, what about "sacrifice a plains" which you should have for the CIP and is somewhat flavorful for "wandering" other lands.

Converted mana cost instead of power maybe?

How about 2 clauses:
All spells gain "As an additional cost to play ~this~, empty your mana pool."
If a spell would resolve, remove it from the game instead, unless that spell's controller empties his or her mana pool.

You tap with upheaval on the stack.

I dont really have a problem with hitting 1 non-basic at 2, but the loses 2 life part definetly has to go as it isnt in flavor for either of the colors.

"Each player can not play spells or abilities if his or her mana pool is not empty and he or she has a spell or ability on the stack."

Nice find, Godder .  I've never even heard of that card.

Interesting how that order can be changed isn't it? So it shall be...

If you're floating mana then you probably dont have enough mana total to play your instant or need to wait for another spell to resolve so I see this being very rarely played around despite it being a triggered ability.

In my understanding of the rules though, Nightmare has a static ability that you would want to somehow word Manor to say that the artifact "has" or "gains" text similar to that.  I tried to add more of an explanation for this but it is very frustrating trying to find an example and it would probably be best to just ask in the rules forum or pm jebus as he is far more knowledgable about this than I.

I guess thats what it will be then.  Clock.

Does this wording set a specific p/t at the time of resolution or will the p/t flucuate with the number of structures?  Either way I dont see a need to have the artifacts de-animate, just curious.

Just...no.  Losing players already get to choose play or draw and I dont like a card that carries effects from one game to the next.  Also it should at least specify something like "last game in this match" or there are horrible memory issues.
EDIT: I think the real problem is that this just seems like an unglued card.
