Each new card should be based on any previous card entered, and either:

1. Change the name and optionally color while keeping everything else nearly the same, or
2. Make a new card with the same name as the old card.

Notes:

• Include a number in the name (eg. Magnetic Mine #2 ) for disambiguation when necessary
• When you change the name, you may colour-shift the card and make other small tweaks to tidy up the templating or maintain the colour-shift, provided you keep the same spirit: eg. change sorcery to instant, change non-black to non-white, change coloured spell to artefact with tap, sac.
• You may choose any card in the thread, not just the most recent one (this is an experiment, I'm not sure how it will go)
• If no-one responds for 24 hours you may choose a random card off gatherer and add it to the thread
• I don't have much time to play referee, so if someone asks what's ok, other people please respond with your own best judgement.

The randomly chosen starting card is: Magnetic Mine

­Magnetic Mine #2 to show you how it's done :)

The next could either be another card with that name, if there's any more ideas to be mined out, or a new flavour for my card (or the original card). Note: I allowed the rules to turn an artifact-sac into a coloured spell because otherwise I think it's too hard to switch between colours and colourless.

I'm game. I added Bamboo Rocket Hedge based on the ability from Magnetic Mine #2. And while it wasn't part of the challenge, I took the time to add flavor text. Made sense to me.

Oh, and just to be confusing, I also made Magnetic Mine #3.

My Mine Magnetic Mine #4.

And Bamboo Rocket Hedge #2 inspired by Bamboo Rocket Hedge because one Bamboo Rocket Hedge in magic isn't enough :)

And now we have a creature to riff off if people want.

Created Trostani's Decree based on Magnetic Mine #4.

I created Trostani's Decree #2 based on Alex's Trostani's Decree.

Added Regenesis based on Trostani's Decree #2.

Link added Regenesis #2 but forgot to link it. I added Magnetic Mine #5.

Created Regenesis #3 based on the intriguing name of Regenesis.

Added Phoenix Flame, based on Regenesis #3.

Added Phoenix Flame #2 and Peek into Hell and Dangerous Revivification both colour-shifting Regenesis #3

­Viviana's Resuscitation based on Dangerous Revivification

Created Mirage colourshifting Regenesis #2 from GU to U. and Vesuvan Outpost shifting it from GU to colourless.

Added Makes Me Stronger, based on Viviana's Resuscitation #2. Oh, amuseum didn't link to it here. Well, consider that amuseum's link as well.

I submit Undying Evil based on Viviana's Resuscitation #2, since wizards happen to have already done the work for me in that case :)

­Viviana's Resuscitation #3 based on Viviana's Resuscitation. A can't-lose-the-game for enchantment decks.

­Bamboo Rocket Hedge #3 based on Bamboo Rocket Hedge again :)

­Shelter of the Sun God based on Viviana's Resuscitation #3.

I made Mirage #2, following Mirage.

­Land Grab based on Mirage #2

Added Phoenix Flame #3 and Shelter of the Sun God #3.

I created Regenesis # 4, which amuseum turned into Vindicated Path, which inspired Vindicated Path #2.

Added Vindicated Path #3, because I, too, can't leave well enough alone. :)

And... Phoenix Force #4, thanks to some intervention by Challenge # 073.
