Potential support champions to use.

Q is really good at engaging and continuous knockups with slows on E. Plus, free GA if it all goes wrong.

AD Reds, armor yellows, 3 flat CDR blues, 6 MR blues, 3 flat CDR quints
Gragas has 3 forms of CC, 2 of which are hard AoE. Long range slow/poke and pretty good engage/disengage.
0/12/18 CoC Keystone
MP reds, HP@18 yellows, armor quints, mr blues
Good engage with R along with a sivir ult, a pull when linked successfully with Q while being sticky towards champions with E's 2 dashes
0/12/18 CoC Keystone
AD Reds, armor yellows, 3 flat CDR blues, 6 MR blues, 3 flat CDR quints
Q poke/slow, W for AoE snare, E for engage and R for single target freeze/AoE damage or self freeze when in danger.

Q/R for multi-target engage, E for slows. Great roamer

Manaless, Constant poke, situational stun but AoE R with a speed-up from E is very game changing. Bullshit champion.
12/18/0 Thunderlords keystone
MP reds, armor yellows, mr blues, movement speed quints (trust me)
Q AoE slow in a straight, wide hitbox; E w/ AoE knockup, R AoE knockup. PAssive when it all goes wrong. Roam a lot. Get jungler to gank lanes with you. The constant fear of a Zac + jungler coming to lane will make everyone shit their pants
(RUSH THIS SHIT, START ROAM LVL3)

Now before you shove your foots down my eyesocket for this, hear me out. If MF can become a support, why can't Varus? Q poke, E poke/slow but more importantly in skirmishes he does %HP because of his W. His ult is also great AoE snare(1by1) but very good at engage/disengage. Trust me.

Give these a try and let me know what you think ^^
Armor shred, attack speed boost, AoE slow with a Sheild, arena, flag'n'drag is a knockup.
