Interesting Character concept

Bruiser tanky/melee fighter, toplane, with a kit revolving around his sword, which is not tethered to him permanently. Concept: A knight, who has fought in numerous crusades and campaigns, found an ancient, powerful, magical sword on one of his missions, which he now uses to cut down his foes on future campaigns. His kit would stand out due to his sword being not attached to his character permanently. For example, his Q would throw his sword to a target location, and while his sword is stuck in the dirt, he wouldn't have it, lowering his attack damage but increasing his attack speed. He can walk over the sword stuck in the ground to pick it up again. Example kit: Passive: While in possession of his sword, every fourth basic attack deals bonus magic damage Q: The knight swings his sword 3 times (similar to riven Q) in 3 activations. On the 3rd activation, he slams his sword overhead, bringing it down on the ground in front of him (like illaoi Q) stunning all enemies. W: Tosses his sword at a target location, dealing aoe damage and sticking his sword in the ground. E (while in possession of sword): Hurls his sword in a skill shot in front of him (like Olaf Q) with it landing at the target location. E (without possession of sword): Skillshot tackle, if he collides with an enemy champion, he knocks them back a short distance and stuns them briefly. If the tackle is used upon the location of the sword, he unleashes an empowered slash upon finishing the tackle in an aoe around him. Ultimate: Unleashes the divine power of the sword, causing it to grow and erupt in flame. Basic attack range is extended, and basic attacks deal additional magic damage and cause the target to burn. Additionally, enables a single activation of an aoe slash in a cone in front of him. I just thought this up and thought it would be a really cool champion design lol what do you guys think?
