>>30401355The basics of SOS chaining are False Swipe and a good single target attack.
First you get the Pokemon worn down a bit, FS is a good move for this.
Then try to stall until they call for help. This is where you would want to use Adrenaline Orbs, it supposedly increases some odds that the Pokemon will call, and help will come. Some good tactics for stalling are repeated use of the Adrenaline Orb, which actually does nothing and doesn't seem to consume any orbs beyond the original one used, or just swapping pokemon.
Then you're just in a cycle of taking out one of the two pokemon and leaving the other alive to call for help, repeat ad nauseum.
Note: if you're chaining for shinies, and maybe Hidden Abilities, you need the base pokemon and the called pokemon to be in the same family/species. I'm not sure how it works for Mareanies.
A good Pokemon to consider using is a Damp Parasect, but you'd have to chain for one in the first place. Don't use Effect Spore, it can mess up your chain, so Dry Skin is an acceptable substitute. A basic set-up is False Swipe, Spore, a single target attack like Slash or something, and whatever you need as a 4th move.
Some support Pokemon that you want would be: an obvious Synchronizer if you're picky or trying to chain for a salvageable shiny, a pokemon with a skill or ability (Trace, Skill Swap, Role Play, Worry Seed because it lists the ability before turning it into Insomnia, though that could be counter-productive if you're relying on inducing Sleep, or possibly Gastro Acid if it also notifies you of the foe's ability before it is cancelled) to test for any desired Hidden Abilites, and a Pokemon that can run Wish/Heal Bell/Aromatherapy support, because chaining can go on for a while and you'll need to heal your own Pokemon at some point.
One set-up that I've seen for a good Smeargle is False Swipe, Soak to FS Ghost and Steel types and to Spore any Grass types, Spore, and Gastro Acid.
