Maybe this is a nub question, but I never tried S. or R. Swap in clan, so how it works? I swaps my poke into another poke or my money into a poke? And what's the difference between the Random to the Specific Swap?

specific swap is you get a poke you want random swap will give you a random poke wich could be one you dont want. in the clan i dont think it gets rid of the first poke but on the left of the page where the gyms are the specific one gets rid of what is 1st slot
