Magic Damage Crit Items

So, I decided to make a few items that basically allow magic damage to critically strike. These are just for fun and I didn't put that much thought into making them balanced or anything, so don't tell me in the comments stuff about how they're broken or strong, but only good on certain champions or whatever. I don't wanna hear it and I don't care enough about your negative comments. Just sit back, read, and wonder who might actually make use of them other than Azir and Aurelion Sol. With some more effort into balancing them and a few more items, these could be viable on a number of AP champions.
