Karthus has only now reappeared in the list of champions of Truth Arena season 10 since his appearance in the first season. He will be a Pentakill Executioner with deadly Requiem like season 1. And of course he will occupy a main damage position at the end of the team alongside other options like Caitlyn DTCL this season 10.
From season 1 to season 10, there have been quite a few changes, so you will have to learn about Karthus from the beginning to see what he needs and which DTCL season 10 squad best suits him. Scroll down below to review how to play Karthus DTCL season 10.

Karthus squad, build Karthus TFT season 10
Pentakill
There are 7 Pentakill generals that you can bring into the team, 7 Pentakill is enough to support Karthus. You can even use another champion if one of the 7 Pentakill champions is a Super Star champion.

This team will depend on Viego, Karthus and Yorick for damage, but you should focus on Karthus and Viego. Yorick can be just a secondary champion to stimulate the system and support armor reduction and physical damage. But if you see many Yoricks appearing, you should capture many Yoricks to overwhelm the damage at the end of the game.
Executioner
Compared to the squad above, the Executioner seems easier to complete because there are fewer high-priced champions. Going in this direction, you can flexibly choose Akali True Damage and Akali K/DA. This team's damage sources will include Karthus, Samira, Akali and Twitch, with the rest mostly supporting resistance and stun.

Karthus will be a late-game 4-cost staple if you are aiming for Executioner or Pentakill and have magic items from the beginning of the game. However, he will probably be sought after by many people, so you should pay attention to see if anyone plays Pentakill and Executioner from the beginning to quickly get to level 8 to welcome Karthus into your team.
