I edited the post in there so it reflects who did the art. I didn't see who did the art when I found it the first time, so thanks for finding that for me. In all seriousness, I never intended to steal anything, and if I have broken a law, please show it to me, because I am not entirely familiar with how a copyrighted piece of art should be handled when it is so freely available like this. Clearly we all need to learn about this if it really is serious, because it was stated in the card idea contest rules that the art didn't matter and it was okay to borrow an image.
I eagerly await your reply.My vision for the card came in stages. At first I wanted to make a creature called "Shield Bearer", a sort of squire type that would "equip" a shield, destroying the shield and freeing up your shield slot, allowing you to have two shield effects simultaneously. But I felt that would be ridiculously overpowered, so I made it so that when he equipped the shield, he gained the gravity pull status as well. I was content with that for a while, as it made a sort of living meat shield with defense, but I didn't like how it made your own shield slot useless, so I decided to go in a different direction.
I started reading the description of each element and found the description of the Light element.
Light elementals dispense blessings and befriend angelic and righteous entities. Light elementals can exalt their creatures, heal them, or deal damage to death and darkness elements.
I revisited my Shield Bearer and thought about making it equip a weapon instead. Having played this game since the beginning, my first thoughts were about Flying Weapon, as you mentioned. I tried to see if it was possible to create an ability that behaved like a warrior equipping a weapon, while avoiding a "Flying Weapon on a stick" type card. Since Light is all about boosting/exalting its creatures, I figured an ability like "Endow" would be fitting. The ability fits with the flavor of the Light element because it is like the Crusader is calling on the power of the gods to channel the power of the weapon to enhance his fighting abilities.
