"Knightmare Incarnation Idlee" Rating Score by 闇を彷徨う彗星

Judging from the name, is it an evolved form of "Lee the World Chalice Fairy"...?
When the link marker on the field is 8 or more, it has the effect that he can Special Summon from his hand. It's not that difficult if you or your opponent is his deck that uses his Link Monsters a lot. If the conditions are met, he can Special Summon in free chain, but its value follows the effect of ②.
When the opponent has more Link Monsters than you, it has the effect of sending all Link Monsters to his GY. With a large amount of Link Monsters aimed at extra links, his deck can be expected to play a strong role in the meta. If you hold it, it's a story.
As a supplementary effect to level 9, it adds resistance to destruction by card effects. Although it is said that it will be attached, the status is quite poor, so if you stand still, you will be targeted as it is.
It's called a free chain, but you can't go until you get to Link 8, so you can end up with cards that aren't affected by effects or monsters with the effect negate destruction, so don't overestimate.
Of course, if your opponent has a theme that you can fight in the main deck, it will be a bad card in your hand, so be careful.
