I really like the idea of this thread, because if stuff like this is added to the game, it brings in a whole new level of strategy. So, here's my contribution:
Theme:
1)There has been quite a discussion about sacrificing creatures to gain quanta. Why not make a card that sacrifices pillars to gain quanta? It would be a great short term solution, but damage your game on the long term. Not sure what it would be called, but I was thinking maybe a forge, or a power plant of some sort maybe? It would make a cool addition to the "other" cards i think, because they are kinda boring atm
2)an entropy card that performs a mix between the nova effect and the discord effect, so maybe each turn it converts some amount of entropy quanta (maybe a third, or a random amount) into a certain number of random quanta
3)a card that "absorbs" quanta that otherwise would have been produced then releases it later.
4)a card that allows you to go into debt with quanta
Role:
1) it would work as a way for mono decks to get a final burst of quanta when they no longer needed their pillars. It would also allow rainbow decks to get out of some situations where they just need 1 or 2 more of a certain quantum. Prety much a card that can be handy for any type of deck.
2) would provide quanta for mutations without using quantum pillars, adds more randomness to entropy, what more could you want?
3) it would be a risky way of slowing your opponent to speed yourself up (risky because it could backfire -> will explain in mechanic section)
4) this is pretty much just one method that you could use of spending life to gain quanta (as mentioned by at least a few others in this thread)
Mechanic:
1) sacrifice a certain # of pillars in a stack (not sure how many, could be just 1, and it is an ability that can be used multiple times per turn like leaf dragon, or maybe just once per turn, or maybe it would destroy 3 pillars like an earthquake) and convert it into quanta (maybe 3x what the pillar would generate in a turn?)
2) I can see this working in 2 ways:
-like a leaf dragon's effect, except rather than turning 1 light into 2 life, it converts 1 entropy to 1 random (2 random would be pretty overpowered as it could be abused to get heaps of quanta, or just keep going till you get the right kind of quantum)
-it just becomes a passive effect of turning 1 entropy to 2 or 3 random quanta (or maybe a random number of random quanta
) or an ability that can be used once per turn with that effect.
3) It would be either a permanent or a creature that would absorb a percentage of quanta that would have been gained (so, each player earns less quanta, and the amount lost gets stored in the creature/permanent) then when the creature dies/permanent is destroyed then:
a) the person who destroyed in gets the stored quanta
b) each player gains all the quanta that the creature/permanent stole from their creatures/pillars
c) the quanta are randomly distributed between the players (although this favours rainbows quite a bit)
d) the quantums are given to the owner of the permanent/creature
or e) it only absorbs the opponents quantums, but when they destroy it they get their quantums back.
If multiple of this card were in play, the same amount of quanta would be gained/stored but it would be evenly distributed between the cards that absorbed it, so would be harder to recover.
4) during the turn this card is activated (or turns it is active, depending on whether it's a spell or a permanent or creature) you can go into "quanta debt".
quanta debt could work in one of the following ways:
a) when you end your turn (after playing cards, before creature attacks. As soon as you press the spacebar) all negative quanta values are reset to 0 and the amount of quanta you had to gain to bring it back to 0 is subtracted from your life
b) you lose 1 life per 1 or 2 quanta in debt you are (not sure if it should be 1 or 2, or some other value) and you continue to lose life from quanta debt ontil you bring all quanta values to 0 or higher (that way a mono deck, or pillarless deck can't just use this to play a huge amount of creatures first turn).
It would probably come in the form of a spell, and you can't play the spell if you are already in quanta debt. You also wouldn't be able to play cards that "consume all quanta of X type" (fractal, miracle) while that card's effect was active (either that, or you just still need to pay the normal price for the card, and it isn't affected by quanta debt)
well, those are my ideas. feel free to use them/modify them to come up with your own. Hope it helps.
