There are 5 teams in the basketball game, with 6 games in total. How to play is more reasonable?

First, draw lots to select a team to advance directly to the second round. Then the other four teams draw PK in pairs. (So there are two games.

) The team drawn in the first round will play one game each with the two advanced teams, and the two advanced teams will play another game. In the end, the two strongest teams will be selected to play in the finals (is it reasonable for the landlord to play six games like this? )
