Mordekaiser Runes & Kayle Support Runes
Mordekaiser1: http://na.leagueoflegends.com/en/featured/preseason-update/8000-8008?build=01110016
Every time you get into a fight you will get those 3 auto attacks off. Gain an extra 20% tenacity and heal off kills + do more damage to tanky stuff. 15% spell vamp without having to invest 3400g is AMAZING. Ghost Poro to synergize with the Mordekaiser thematic.

This build is for being more tanky and supporting the team with font of life, Rylai's is a must though. If you have Rylai's + Font of Life your ghost pretty much life steals which is crazy. Maybe throw in a ardent censer as well and then tank up.
Kayle1: http://na.leagueoflegends.com/en/featured/preseason-update/8300-8351?build=40100326
I've always ran high amounts of A/S on Kayle support for early game dominance (her autos are equal / slightly better than most marksmen early on) and to apply Rylai's consistently. Glacial Augment means that I don't need Rylai's anymore and can build other core items sooner. Biscuit delivery sounds busted for early lane pressure, you can force trades early and hell they don't even have to be good trades. Once the biscuit is deployed you will heal up and can build hard advantages off that. Magical Footwear because you save like 350g and get better boots. Cosmic Insight just cause.
If I spec into Ardent though it negates the loss of attack speed. Font of Life AND Ardent now apply to yourself meaning free A/S and some extra damage which is always nice.

Press The Attack is adaptive. Even as Kayle support I've gotten many auto attacks off without buying many attack speed items most of the time. Safely stack up AP and increase the value of the heal and even auto attacks potentially. 100damage per second is nothing to sleep at even from a support. Triumph for the sustain from take downs, supports rack up a ton of take downs. Cut Down to help the team a bit. Legend: Alacrity + Ingenious hunter so for stacking fun. 20% attack speed from alacrity on it's own, 32% if you stack if with the domination path.
Zombie Ward because maybe, poro ward and eyeball collection are both viable. Ingenious hunter because 31% item CDR. When I don't go stoneborn pact (font of life) I go windspeakers and buy a bunch of actives like mikael's and redemption. 120s CD on Mikael's % Redemption becomes 71s! With Ruby sightstone it becomes 57s.
Example Build:

Basically you don't go into resolve if your team can't take advantage of Font of Life.
