How does the shared champion pool mechanic in Teamfight Tactics work exactly?
Does it work the same way as Dota 2 Auto chess where when a hero is bought, it removes 1 out of the 50 heroes that are in the champion pool, Then returned when sold or lost due to a defeat.
Or does it work by how many times it appears in the shop, and reduced by 1 for every copy of the champion that is found.
