A new support champion

New support champion idea. A guy who has a pet shadow dog who assists the adc. His q is an ap skillshot slow which deals damage. Also when his q hits his shadow dog gives his dogs next attack an lichbane-like attack for his pet. For his w it is a sheild that sheilds himself that scales with ap. If he shoots his q while the sheild is active it will throw the sheild. if the target hit is an ally they will gain the sheild, if it hits an enemy it will explode dealing aoe damage and deal the damage of q. His e is control for his pet being able to click an ally having the pet assist his allys attacks for extra damage equal to the shadowdogs ad. Heres the kicker. This champion doesnt use normal market items. Thats his passive. The only way for this champion to get any armor magic resist ability power or attack power is fromt he shadow dog. Part of his e passive is that for each kill the shadow dog killed or assisted in he gains 1 ad. The champions ap is equal to the dogs ad. The champion or the shadowdog does not gain armor or magic resist per level. The shop will sell items that give either magic resist or armor equal to a % of the hounds ad. there will be no item for the hound to gain armor while the champion cannot gain magic resist. For the final move R, The hound and the champion combine to gain the magic resist that the hound has and gaining the health pool of the hound. it will also change the champions moves slightly. In an average game you get a maximum of about 250 minion kills so the most damage the hound can do depends on the the length of the game but this would be an extreamly fun support class.
