Yordle Champion Concept WIP: Help Welcomed

So I've been working on a for a good while support, but I came up with this Yordle with what I think (don't know about others) that would be really interesting to see in League.

So here's the rundown. Keep in mind, I came up with this faster than other champions I've worked on. Hope you enjoy.

Guin (pronounce like Gwen), the ???

Passive - ??? Carries 3 Relics. 1 large, 2 small. Think of a magical stone looking like something from Atlantis, somewhere along those lines.

Q - ??? Cost: 50/60/70/80/90 mana Range: 850

Guin tosses one of her smaller relics in a chosen position, dealing damage as it lands. The relics return to her whenever she gets too far away.

Active: Guin uses sorcery to toss one of two smaller relics in a chosen position, dealing 60/95/130/165/200 (+60% Ability Power) magic damage. Guin can toss both of the smaller relics, then throws her initial relic next. Ancient Thunder expires when the smaller relics return to Guin. This spell can be cast while moving.

Passive: Smaller relics move up to 40% faster the closer they are to enemy champions.

Cooldown: 13/12/11/10/9 seconds

W - Ancient Thunder
Cost: 30 mana plus 14/22/30/38/46 mana per second Range: 900

Guin activates the power of her relics, unleashing a hidden energy, and damaging her enemies.

1 Relic: Activating while the smaller relics are with Guin, a laser will blast from the large relic. After a .75 delay, a laser is emitted, dealing 30/75/120/165/210 (+40% Ability Power) magic damage and slowing them by 20/25/30/35/40% for 2 seconds. Toggle: Having one or two of the smaller relics out connects the laser to all the relics in play. Enemy champions caught in the stream are dealt 140 plus 60/80/100/120/140 (+20% Ability Power) magic damage per second they are in the stream. When activated with all three relics, enemy champions caught in the initial blast are stunned for 1 second. This spell can be cast while moving.

Passive: Guin gains 20% more magic resist and armor if she strikes herself with the stream. Guin gains 10% more movement speed as a bonus if she strikes herself with the stream when all 3 relics are in play.

E - ??? Cost: 80/95/110/125/140

Guin moves the largest relic around her in a fixed orbit. The largest relic’s speed is slowed when activated with Ancient Thunder.

Passive: The largest Relic acts a substitute for Guin. Negating certain skill shot abilities, but has no affect against AOE abilities or targeted abilities.

Clarification: Guin can use the relic to stop certain CC. If Blitzcrank pulls, and the large relic is in the way, the ability is negated. Stuns or slows like Veigar’s Event Horizon or Thresh’s The Box, can also be negated if Guin has the larger relic in front of her, however, it can only stop the first instance, the relic will not stop the next occurrence if she crosses it again.

Cooldown: 5 seconds

R - ???

I haven't come up with a unique passive or ult yet. But I would love some feedback. This champion sounds simple in my head, but I need outside eyes to take a look into it.

Appreciate any and all help. Thank you for your time. Have a good one :)
