Chromatic Star
For those of you who have this in your format (multiples?), how do you like it? How good is it for your mana fixing, and what fixing suite do you run along side it? Other nice synergies? What sort of decks (2, 3, 4+ color, aggro? midrange? control?) in your format want this?
Okay thought experiment here: I run a fairly "standard" Riptide Cube. If I replaced, 1-for-1, my double shocks for double bounce-lands, would that work? Are there other environmental factors that I would need to consider heavily?
I honestly think bounce-lands are super interesting and maybe...
Do you mean like a set cube? Typically you take 4x commons, 2x uncommons, 1x rares and mythics.
Cut the game-ending GRBS bombs, sprinkle in either extra fixing or extra solid uncommons to replace those cards.
After that, it's up to you.
I would try
Parallel Lives
for starters if doubling tokens is something you think you'll want. Doubling Season tends to be GRBS (or a minimum very annoying) with Plansewalkers in my experience.
Emerge seems pretty awesome with the spawn makers. My first CubeTutor run is basically trying to:
Kozilek's Predator
Decimator of the Provinces
for the win, or to machine gun the villain down with Blood Artist and spawn.
Say you ask RoboRosewater to generate, say, 1,000,000 new cards. Then you ask it to map the new cards to an existing Riptide list based on their mana cost, type, etc. Boom. New, "functional" cube each time.
With the right initial conditions a procedurally generated Cube could be super interesting. Maybe BTP should look into integrating RoboRosewater to create a large pool of new cards then curate them into a cohesive 360 cube.
IMO this would be about perfect if she couldn't blink your own creatures.
She also happens to be very good against Control Magic variants, which are fairly common in cubes.
