Like Illaoi or Zyra, I plan to make a champion that interacts with objects. Their definetly a mage, but unless this object is ranged or can be moved I dunno how they would be effective. If their ranged its too much like Zyra I feel. I want them to amplify his spells and be used as conduits for casting.
Honestly, this sounds very similar to 
or 
since it will be a movable object instead of a stationary like 
or 
.
Not saying it doesn't work because those two champions are among the highest played competitively and solo queue.
My only suggestion is finding a theme, and center all of your abilities around this object/objects.
I'm working on a champ that can second cast their abilities to place "totems" that do things to allies/enemies in range
Just brainstorming some ideas for the cloud theme :P
Passive: [The Cloud] Bob is accompanied by a big cloud, which is the focus of each of his abilities. When moving away more than X distance the cloud will start to slowly [speed depends on distance] drift in your direction. [Brewing Storm] Bobs resource is "moisture" and max amount increases with level and X, moving the cloud generates "moisture" [increased gain in river]. Max amount of moisture is the size of the cloud and current amount is represented by the color of the cloud [black is full and white is empty].
The cloud regularly [frequency depends on current moisture] releases thunderbolts to hit the nearest enemy (prioritizing champions).
Q: [Guiding Wind] Bob summons a jetstream in an area that moves the cloud and any minion or champion into it's direction (cast like viktor laser). Displacement increases on the cloud and when the target moves into the direction of the stream. Spammable - Multiple Winds can be present - X (+rank) duration
W: [Clouded Judgement] Bob disperses the cloud into a big area for x seconds or until you cast the ability again. Mist radius increases by size over duration, heals allies and applies damage and nearsightedness to enemies inside it.
E: [Thunderstrom] The Cloud shrinks/turns completly black and unleashes multiple thunderbolts [amount depends on spent moisture] at a rapid pace Cost is current moisture
R: Passive: [Cloud Momentum] The clouds speed and moisture gain increases each time an ability is used. Stacks X times - new casts refresh duration
Active: [Wanderer of Clouds] Bob jumps onto the cloud refreshing the current effect to max duration and putting him in stasis for a short duration. [The cloud continues to move in it's earlier direction]
than summonable interactable pets 
FloRaider out 
Edit: Sry for the wall xD
