If you haven’t noticed, the 6 Shadow team composition with Shaco as the main carry has actually been relatively nerfed in patch 10.7 with the rework of this trait. Previously, due to the ability to stack damage percentage, it was normal for 3-star Shaco to deal over 10,000 damage (or more). After the rework, Shadow now only adds basic attack damage, so the damage output is no longer explosive and this jester is much easier to counter.

However, Shaco is still an incredibly strong champion whether you play 6 Shadow or 6 Assassin, with the ability to make enemy pieces lose their target and deal critical damage. Because of this annoyance, in the latest updates of Teamfight Tactics on the PBE server, Shaco has been hit hard with nerfs at level 3 stars, while Master Yi, Zoe, and Rumble have received relatively strong buffs.
