The above ideas don't necessarily encapsulate the feature of the stack that a spell on the top must resolve before the other is allowed to resolve. I also was thinking about basically what I was theory crafting was turns with limited actions.

There's been a surge of new TCGs lately which is awesome to see how new designers tackle the medium. It has gotten me thinking, though, about a piece that's getting left behind that I really enjoy. Slinging spells from my hand at instant speed.

Or like how in Yu-Gi-Oh Monsters are sacrificed to summon stronger monsters, maybe cheaper spells can be consumed instead of resolved to fuel more powerful magic. But how is that mechanic used to create magic type identity (like the color wheel)

I like lorcanas ink system as well for how it gives you important in game decisions to make, but it doesn't allow flexibility of deck building. You are locked to 1 or 2 colors per game rules. There is a world where there isn't a resource, but casting spells requires other costs.

One thing I also really like about magic is how building your mana base determines what kinds of cards you can put in your deck and more complex mana bases often have a downside of being inconsistent or slow.

I like the relic idea because you could have a set of neutral defenses that are randomized and even do a thing where each player also adds an enchantment to start the game so that win con is always slightly different each game.

Like what would powerful wizards be fighting over? There's killing each other. Maybe claiming a powerful relic and it has a set of enchantments to disarm, but your opponent could try and stop you. Of course decking your opponent as a way of saying "none of your magic could compete with me, you lose"

I feel my above example of breaking the stack down makes the spell slinging more like spell slogging. Also how do resources work? Is it mana based? Something else? Card drawing? Traps? Auras? It could also be interesting to have multiple win cons.

This idea that over multiple turns you both are building up to something and then in 1 turn there's this huge fight that exists only during the combat step or end step and once it all resolves you go back to your normal speed. It's exhilarating.

Perhaps spells take several turn to resolve on the board or even have multi stage resolutions before they dissipate (like how sagas work in mtg). I do think part of the fun of the mtg stack is the speed of it.
