This profile has a key for Cyber Sleuth Lucemon. Thing is, Lucemon in Cyber Sleuth is literally no different than your regular 1-B Lucemon, it suddenly being put at above True Yggdrasil is very simply an outlier.
On that note, the profile also has a section for Re;Digitize abilities, despite the fact there's no Re;Digitize key. Considering Re;Digitize Lucemon IS different from the regular one (having absorbed other Digimon to empower himself and all), THAT one needs a key.
Also, it needs to be added to the last key that True Lucemon is True Yggdrasil's equal, being the darkness born from the Idea to match Yggdrasil's light.
