A couple of new champ ideas

An idea for a new support/tank champ. I think of this guy as the rift custodian. His primary role is kind of like a maintainer of his teams interest. His ult would be able to repair damages turrets up to a certain amount and could speed up the recovery rate of a down inhibiter. He would also be able to shield his allies and minions and have one move that could damage and knock up. The next champ would be a mage champ. I haven't come up with all of her move sets yet, but the main thing with this champ is the her moves change according to the seasons. Fire for Summer, Wind for Fall, Ice for Winter and Earth for Spring. Say she has one move that when it's summer can burn an enemy, but in winter will freeze them. This concept could actually change her role based on the season in the summer she'd be a solid mid, but in the winter she'd be more of the support.
