The third game changed mainlyhow the poke assists worked in terms of how captures went, the circling was the same, but assists were no longer a moded top but you place the pokemon down on the screen and it does its own attacks and has its own AI for each mon while still circling the target. Each mon has a cooldown after is is done, allowing for you to use it again if it was not hit, this is different slightly in multiplayer. TLDR assists got better and each pokemon had different effects not just sn asdist based on their type.
