Golden Rule cards

[Koby]

Survery says Masako was pissed when they printed Village Bell Ringer.

She didn't find that joke funny.

Made. My. Day.

R&D question: What would Masako the Humorless' P/T need to be in order to see legacy play. I say the following

2/4

or

3/3 possibly

I know it's been a long thread, but Word of Command, Masako, and Laboratory Maniac have all been mentioned. I suggest Ctrl-F or the 'Search Thread' thingie.

Misthollow Griffin: Definitely invokes the Golden Rule I think, though the Rules do make reference to the possibility that spells could be played from elsewhere than a player's hand. (And while there's nothing else that can be cast from exile, there's several cards that let you cast them from the graveyard, which breaks the rule in the same way... and Panglacial Wurm from the library, now that I think of it. And Miracle cards.)

I'm not sure I understand the criteria correctly, but I hope I do
So here are the cards that come to my mind:

Gemstone Caverns
'leylines'

There is in fact a section explaining how to deal with cards that do things before (or when) the game begins, but nice thought.

Serum Powder

I can't remember if I read anything about this, but it definitely belongs on the list for the uniqueness factor alone.

Animate dead

I think this is just weird, but not rule-bending.

Command tower (it's legal in eternal formats and generals - not)
Steamflogger Boss

The rules do describe alternate formats (frequently enough that I started skipping over those parts because I didn't care) - and even Contraptions! Though only to mention that they "exist".

Also cards that mess with expansions
city in a bottle
Apocalypse Chime

These are within the Rules -- expansion symbol is a relevant property of the card -- but def unique, along with Golgothian Sylex. Albeit "Whenever a nontoken permanent from the Arabian Nights expansion other than City in a Bottle is on the battlefield, its controller sacrifices it.", while I think it's a triggered ability, is unique among all Magic cards, so plus points for that one.

cards that have weird erratas
Lion's eye diamond

Don't think there's anything special about this one.

Reserved list might have some more interesting examples.

Another thing is that rares are much more commonly "interesting" than less-rare cards, but that's still a lot of cards to look through manually.

And in the Mirror Gallery vein:

Brothers Yamazaki

[Humphrey]

[Illissius]

I don't see what's special about Goblin War Drums, but the others are definitely interesting, thanks!

I wonder if there's an extended discussion of "as though" clauses anywhere in the rules. I should check that out some time...
