New Champion Brain Storming :)

I would like to see a new champ come out that could be played as a support/top laner. Ability's include:

Active 1/Q) Borrows under the ground for a few seconds becoming unable to be targeted or hit by AA (interesting exceptions would be Braum's ult which splits the ground, and maybe even karthus' ult). While underground the champion gets a movement speed reduction but can still move around under the ground. But not through walls (exceptions could be things like Anivia's crystallize, or Trundle's pillar of ice). The ground under which the champion passes will be softened for a few seconds, slowing units that travel over it (introducing an interesting chasing mechanic). This ability can be used for re positioning and dodging.

Active 2/W) The champion will take earth and use it to shield an ally or their self. The shield will block physical damage, much like the summoner spell barrier.

Active 3/E) The champion throws a earth and stuns the enemy unit it first hits briefly. This will be a medium range skill shot much like Braum's Q.

Active 4/Ultimate) The champion smash down the earth under them producing a circle around the spot they smashed with a radius similar to Jarvan IV's ult. The earth is literal dented down, creating a crater in the ground. All units that travel from the circumference to the middle (in) will have increased movement speed, but all units traveling from the middle to the circumference (out) will have reduced movement speed.

Passive: This champion runs on soil, not mana or energy. While underground (during the Q ability) the champion will collect soil depending on how far they travel, which will be used to fuel other abilities. The Q requires no cost. The W requires the most cost. The E requires lesser cost. The ult requires a medium cost.

The champion is relatively straight forward but will be hard to manage soil. The point is you have to be collecting soil in order to use ability's which will make it hard to farm (ideal support), and his other abilities are more utility. I was think the champ could be a mole, or bug or something but surely there are many ways to make it look cool and still make sense and function.

This is just something i thought of, I would love to see something like this happens and to know what the community thinks of it. Please comment on my ideas, thanks for your time :)
