Creating an Auto Battle (similar to auto chess / TEAMFIGHT TACTICS)

Hello, First I would like to apologize in advance for my English.

Now I would like to know how I can select and raise a character as it is done in TEAMFIGHT TACTICS?

Thank you with all my heart if anyone there can help me sending images in BP how to make this system.

ps: If someone also wants to send an example of a system where the character automatically attacks the clock at the end of the count, help is welcome too!
