Turf war: black belly skatepark, salt spray rig, kelp dome, bluefin depot
I like using these to practice with the splat chargers, especially the kelp in rig with the ink coverage a sprinkler gets on the crane.
Rainmaker: port mackerel
Using the slasher deco, blocking routes with the sprinkler, kraken, sloshing over crates, and having a clear-ish idea of where each member of the other team is in advance with the linear paths, this is just such a fun one.
Splat Zones: camp triggerfish, ancho-V games, bluefin depot
Camp triggerfish has zones that can both be covered from one side by my main three weapon types, while also providing the option to flank while most of the other team is distracted with covering both zones from the same side. With ancho-v, I love how much it changes from most other versions. The walls that are added are perfect for cover while tossing over bombs and sloshing, while the middle area turns into a little arena more often with that being everyone's focus. Bluefin depot is fun with the randomly placed zone and the viability of sniping, ninja sloshing, holding down the main area with the mini splatlings, or flanking from the side opposite the zone.
Tower control: piranha pit, kelp dome, bluefin depot
Piranha pit is interesting in having to hold down a certain area much longer than most other tower control stages, kelp dome just has so many options (not to mention this is the only ranked mode where I do not get lost among the plant corridors), and bluefin depot is just enjoyable for some reason I cannot think of.
