auto attack

An auto battler, also known as auto chess, is a subgenre of strategy video games that typically feature chess-like elements where players place characters on a grid-shaped battlefield during a preparation phase, who then fight the opposing team's characters without any further direct input from the player.
The genre was popularized by Legion TD in late 2000s and saw other games in the genre released soon after by more established studios, such as Dota Auto Chess, Teamfight Tactics, Dota Underlords, and Hearthstone's Battlegrounds.
