I know, we've been to relatively peaceful planes were most cards are productive tools and good stuff rather than war machines (Kaladesh's first set was all about exploring a city in a golden era of innovation) and it was one of my favorite sets to date just because of this.
This set, however will never reach any particular armed conflict like Aether Revolt did, it will simply be about predatory economic systems, trade and commerce. As you may have already guessed, I'm an economics major, so this stuff is exciting to me, and I would love to make it exciting for everyone else. POSSIBLE RETURNING MECHANICS
Some returning mechanics that i'm initially hoping can appear are:Treasure tokens
(This is an obvious one, treasures are already evergreen and flavorful)Food Tokens (These are new, however, you can't tell me they aren't perfect for this set)Populate
(Population growth is an important factor of markets)Energy (Energy arguably is the single most relevant factor in developing economies, this is also a good chance to fix that mechanic) Prolferate (Another recently printed thing, but it has synergy with energy)Buyback (It has the word BUY in it, lol. But, really it makes you administrate your mana)
Obviously the set can't contain all-recycled nor so many of them.POSSIBLE NEW MECHANICS
Some things that I would like to add that increase interaction Card draw tradeoff.
Basically, you give your opponent the choice of drawing cards in exchange for increasing your spell's power. This was mediocrely explored in cards like Bargain. Occupy
(Gain control of target land youdon't control until this permanent leaves the battlefield/Until end of turn. Untap it)
I looks like an easily problematic mechanic, but I think this is the set to try it.Randomizing/coin flipping/die rolling
The markets are very sensitive playthings, you never know what will happen next for sure, random chance isn't an strictly red thing, maybe all colors can have some.Full moon
(It is full moon every third turn. If players aren't counting, it becomes full moon and start counting)
Natural cycles matter for productive activities, I designed this for a werewolf mechanic, but it really adds a very simple timer that changes the way players act, it makes them wait for the perfect moment. It doesn't have to be named Full moon.COLOR PIE
Black: Black markets, illegal activities, predatory capitalism.
Red: Arts markets, gambling.
Green: Agriculture, seasonal cycles, resources.
White: Legal frame, organiziations, equality.
Blue: Innovation, Exchange.POSSIBLE PLANES
I wouldn't mind a return to a plane, some of my top picks are: Kaladesh
(As I said, this was a heavy inspiration)Innistrad
(It is still rebuilding from all the mess that happened there, this is a good moment to recover )Ixalan
(I live in latin america, it is well known that it was after conquest, competitive markets took over)Fiora
(Italian reinessance is very evokative of commerce)Segovia
Otherwise, if the plane is new, i would really like it to be centered around the sea, like a caribbean style thing.
What do you think?, I've never made a full set before, I need criticism.
