@Link: I've thought of that. It doesn't seem likely, but I'll probably try that avenue first. If I did, I could expect another round of heavy playtesting, though, thankfully, I would either be uninvolved in that process, or thrilled by it.

@dude: Hmm... looking up Mercenary. Found this old Alongi article on it: http://www.wizards.com/Magic/magazine/Article.aspx?x=mtgcom/daily/aa78
Interesting. Obviously, Alongi is expecting something closer to 6 casting cost rares, so it can't be that exactly. Maybe I'll make some custom rules that play somewhere in the middle.

The simpler format jmg proposes could be like Mercenary Magic, which had a pile of Treasures that players can purchase.

Sell it to Wizards.

Whoopsies. That was supposed to say 'Graveyard' ala Night Soil. Thank you for that... that card would have been monstrous, no?

As for the game this is from, I've got a homebrew board game by the name of "Enter the Dungeon" that combines Magic: the Gathering with a dungeon to run around in. I've found that without treasures peppered throughout the map, players have a tendency to sit in the main room and cast spells at each other. The treasures are all patterned around 2-3 casting cost spells, so as not to disrupt the flow of the main game. (Being a different card type, they're also really hard to get rid of. Many of them need to be tested. We haven't played EtD in a while.)

I might post full rules to the game here... but it's a bit complicated, and the dungeon tiles are all unique, so I'm waiting until we've perfected it. I might sell it... I'm not sure. It's a tricky sort of thing to sell, since it must be obvious that it plays with Magic, but never references Magic proper. I'll see. Either way, I figured it didn't hurt to add treasures into Multiverse. If anybody else wants to use these for whatever reason, they're more than welcome to them (maybe some format where you can pay or so to get a random treasure? I'll let someone else figure it out.} If I do end up printing EtD, the treasures will all have to change radically anyway.

This isn't a set of Magic cards. These cards are for use in some other game; I can't remember what OTTOMH.

These aren't normal cards, so I don't know the power of this, but looking through your opponent's library seems good. It should shuffle afterward.

"of your choice"? Does this really let you look through any library at will, and not have to shuffle afterward?

Ouch. Goodbye nasty combo deck!

You know, you make me realize that this particular set doesn't need to be private. Unlike a few of the other private sets I have which are ideas for games I'd like to develop, these cards are supposed to be for a Magic-ese format I created, which may someday be it's own game, but may just be a Magic format I created, and stays at that. It's complicated. I'll make a General Post soon so that players have some idea of what I use them for, and what they could use them for instead.

Niice use of the facilities :)
