Looking for a new Evolution
I had one of those light bulb moments when using the word evolution that led to me wanting to create a Magic The Gathering set of cards. Not surprisingly, the set would be called Evolution.
The concept of this set is that certain states in a given game will cause creatures with an evolutionary-type mechanic to semi-permanently alter. To achieve this effect, these cards will have flipsides - one for pre-evolution, one for post-evolution.
So far, my idea for the individual mechanics are:
Competition X: When a certain number of creatures are in play with the given creature, it forces the evolution of that creature. The number of creatures can be general or specific. Eg. a flying creature might have Competition 3 where the effect will take place when 3 other flyers are in play. In this case, it may be that the increased competition of flyers force the flyer to evolve into a land creature. This could be seen as a disadvantage of course, but there could be many examples where the result could be more positive. For example, a smaller creature could become larger or gain special abilities making it more powerful.
Mutation X: When a certain number of sorceries are cast while the given creature is in play, the creature mutates. The number of sorceries that have been cast can be kept track of by "mutation" counters.
Transcend X: When a certain number of enchantments are in play, the given creature transcends its current station.
Spoil X: When a certain number of creatures are put into the graveyard, this will drive the effect on the given creature. This could be kept track of via "spoil" counters.
Trauma X: When a certain number of instants are played while the creature is in play, the effect on the given creature is triggered. This could be kept track of via "trauma" counters.
Of course there are all sorts of possibilities for sorceries and instants involving adding more than one counter at a time, removing counters, forcing a de-evolution, speeding up competition by creating temporary token creatures etc...
And of course there could be enchantments like prevention of evolution on a given creature while enchanted, or instant evolution while enchanted.
There is alot of scope here for an interesting set.
