In the early stages of the match

At the beginning of the match, use Tristana, Senna, Poppy and Thresh to form a basic squad. These are 4 quite comprehensive generals with the ability to deal damage and resistance, so that you can keep blood relatively well during this period.
However, the Devil's Devil is the squad that uses an upgrade strategy, so try to accumulate gold to achieve higher levels.
Middle period

At level 5, replace the Senna with Miss Fortune as well as add Lulu to the squad. Then, at level 6, temporarily use Lux to activate 2 mysteries.
During this period, the majority of the artist generals have not yet appeared, so you need to continue accumulating gold and upgraded soon instead of the generals in the squad to 2 stars.
The end of the match

At level 7, replace Miss Fortune, Thresh, Lux with Fiddlesticks, Ivern, Karma to activate 2 artists and two evil gods. After that, temporarily use Soraka to activate regeneration and the envoy. When up to level 8, replace Soraka with Garen, add Teemo and equip the artist for Fiddlesticks to complete the squad.
Tips and tips
To summon and upgrade Teemo at the end of the match, you have to trade a certain amount of blood. Therefore, try to keep your blood by upgrading and increasing the number of generals as well as the system in the squad right from the beginning of the match.
If you can't find a artist, use Syndra at level 8 and add garen at level 9 to complete the squad. If there is a artist and a 9th level, you can consider adding Lucian or Heimerdinger to activate more artists or gunners.
