I came up with an interesting idea for a champion

Name: Crystal Lore: I'm not creative enough to make a good lore for this champion but I was thinking something along the lines of a beautiful slave girl who's only personal item was a mirror. She's a trickster that one day realized she had mischievious and violent powers. She uses these powers to free the other slaves and to trick the guards etc... Please comment if you have a better idea for the lore. Please no hate or harsh criticism. I just thought this would be a cool champion.

Passive: Pride Crystal's CDR limit is 80% and she gains 1% CDR everytime she damages an enemy champion. (Cooldown = 10 seconds) Q: Shard Crystal fires a thin glass projectile. If Reflect is active, Crystal fires a shard from her clone also. (Damage [%Magic Damage + Base AD] Cooldown 8 at all ranks) _Shard Passive: _ Damaging an enemy champion with shard marks them. Crystal's next Shard can pop the mark stunning the enemy champion for 1 second. If Crystal's next shard does not damage an enemy champion, all marks are removed. W: Reflect Crystal summons a clone that oppositely copies Crystal's movement. While active, Crystal and her clone gain 5%/10%/15%/20%/25% bonus MS. (Cooldown: 20 at all ranks) E: Unbreakable For 0.5 seconds the target champion is put into stasis and reflects 50%/60%,70%/80%/90%/100% of damage taken onto the person dealing the damage. This ability can be self-cast, cast on allies, or cast on Crystal's reflect clone. (Cooldown: 20 at all ranks) R: Sacrifice and Salvation After channelling for 0.5 seconds, Crystal globally switches places with an allied champion. (Cooldown: 160/150/140)

She's meant to be a tricky mage with good defensive utility that scales into a rapid fire mage with her CDR. I think her ult and E abilities are very interesting and could help encourage teamplay.
