I like these, "respond to the previous poster" challenges, hopefully a few more variants on the theme will still be welcome.

Design a card incorporating a word or words specified by one of the approx three previous posters. Then leave a word or words for the next poster to use.

A few details:

• A single word, a phrase, or multiple words which must be used in any order are all fine.
• You can use the word/words on any part of the card, tho' most suggestions will only make sense in rules text.

Note: We're generally relaxed about specifying extra or fewer suggestions, but for this one challenge, I'd like to try to keep EXACTLY THREE suggestions on the go at once. I think trying to meet the restriction can produce simple but interesting cards that wouldn't otherwise be made. So try to:

• Not suggest extras, only suggest one new word/phrase per submission
• It's fine to make a duplicate card based on a previously-used suggested word/phrase, but don't suggest a new word.
• However, if it's been a day with no more answers, assume the previous words were too hard or not interesting enough, and feel free to suggest another one.
• If you answer a challenge but don't think of any new word, it's fine to say "and someone else can fill in a word".
• If there's an accidental double-answer both suggesting a new word/phrase, that's fine, don't delete the second one, but the next answer should not suggest one.

To start us off:

• "Exchange"
• "Minotaur"
• "Win the game"

I apologise, I may have already broken the format a little... I created Lord of the Labyrinth :)

My extra phrase (to replace either "exchange" or "Minotaur") is:

• "return [something] to its owner's hand"

LOL. Look at me not anticipating edge cases :) I think adding one replacement mechanic is the right thing to do.

Ha! All Lord of the Labyrinth needs now is some rider text that reads "If you exhcange a Minotaur with another Minotaur, you win the game."

Added Ascendancy Engine, using "win the game".

Let's see. How about I add "Remove [cardname] from your deck before playing if"

No takers in a day, huh? Okay, the rules state I add one more locked word/s. Let's try: "Protection from Shapeshifters"

­True-Seeing Goggles using "Protection from Shapeshifters".

Adding "becomes a"

­Whelming Nodes

Adding "charge counter"

Made Fuel from Food. Maybe we should add two word/s every other time we pull an Alex? Fine. Adding:

­
• "Target eight"
­
• "continues to shine"
­

Oop. Another 24 hours. Here's another one:

"flying, reach"

Let's try one more time, eh?:

"enters the battlefield tapped"

or, if you're feeling spicy:

"enters the graveyard transformed"

I am going to come back and answer some more of the challenges but I didn't have a chance this weekend :)

"Target eight" is really hard, I can't think of any existing rules construction that would use it apart from "Target Eight-and-a-Half-Tails". I think I'm going to have to allow a full stop, which still doesn't make it easy. But don't change it now, I like a challenge :)

It didn't occur to me when I wrote that that I got the usual wording construction backwards. Feel free to make that "eight target" instead. Or go for hard mode, if you so wish.

That makes sense. I might try both "Eight target" is an interesting challenge by itself.

­Morphlicant was an attempt for "Flying, reach", but it didn't quite work, so that one's still open.

OK, adding Anti-ballistic missile with "Flying, Reach".

Adding new phrase "Repeat this process"

I've been busy over the weekend, but want to come back for some of these. Give me a chance... :)

­Wake the Land using "Target Eight".

Adding "all creatures"

Another not entirely serious attempt for "Target Eight", Drinking Contest :)

How do I keep forgetting gatherer can search for regexes?

Created Grasp of the Octopus for "eight target".

­Dreamspinner using "enters the battlefield tapped".

I think unused words are now at:

"becomes a"
"charge counter"
"remove [cardname] from your deck before playing if"
"continues to shine"
"repeat this process"
"all creatures"

­Mirror Polisher using "continues to shine"

Adding "three piles".

Used "repeat this process" in Revenge of the Blood Witch.

Adding "Name two creature types"

­Helix of Life, using "name two creature types" (but with the correct template). Phrase: "exile ~, then".

­Her with Many Servants using "Exile, then", which I like a lot, but it doesn't quite work.

­Norin, Jr another attempt for "Exile, then" which I really really like, but that doesn't quite work.

Both of those match my intent. "Exile it," "exile cardname", it's all the same.

I created Tamiyo's Dissertation, using "repeat this process."

Adding "would become."

­Ghoststeel Paladin using "Would become"

That was hard, I may have been too stubborn again. I could think of almost no characteristics which become something, and need an effect to happen instead.

Adding "Or more"

­Trifurcated Research using "three piles".

Adding "in a graveyard or on the battlefield".

­First Zombie using "graveyard or battlefield" though I don't think the templating is quite right.

Adding "cards in his or her hand".

Created Wisdom Begets.

Adding "scries."

Created Siphon Thought and Redirect Progress. Partway through Siphon Thought, I thought I wouldn't actually use "scries", so I made Redirect Progress, then realized I was wrong.

Adding "the next time".

Made Bad with Names.

Adding "lose 20 life".

Made Life-cost Demon.

Adding "change the text of"

And I think extant words are:

"becomes a"
"charge counter"
"remove [cardname] from your deck before playing if"
"all creatures"
"change the text of"

Well, if the MTG generator has taught me anything; it's that that's almost a card all by itself:
When ~ becomes a charge counter (some good thing)
remove ~ from your deck before playing if all creatures change the text of (some common thing to change the text of)
