Summoning Based champion

I would like riot (up-vote if you agree) to make a champion that is based around summoning creatures, animals, or other objects.

for example your q can summon an undead skeleton for x amount of time (Based on your AP) with 125% your stats (since this champ is a mage i figure the stat boost is needed for thsi option to be viable.

You w could summon some type of turret that heals and attacks (With boosted stats based off your AP

your E could be a tanky animal of some sort (I prefer a turtle) with effects similar to tibbers but has no aor when summoned (HP based of your AP)

finally you R it could summone a lone of any 1 of your team mates (THe more ap you have the longer it last) With stats taking a 25% reduction so you could have another riven but instead of 100 AD she has 75... Numbers and everything are subject to change. Upvote if you like the idea and please give feedback
