as far as summoner spells go i use flash just to get out of those tricky situations and exhaust to focus the high dps champs in tram fight or when im 1 v 1ing somebody.

item wise... the bloodrazor is a must have with kyle for taking down the tanks on enemy team and just overally focusing squishy easy. kayle is also very good one on one... simple start a fight and when your about to die just use your ult and healing on yourself and hey will probly run away but that when frozen mallet and exhaust come into effect as you can 1 v 1 alot of champs. she is also very good vs infinty edge/ p dancer champs.

as far as runes and masteries go i like to go att speed and a lil dmg for early game aggression. laning with an aggressive partner is key as you will win your lane and take tower mostly every time.

This build works everytime for me long as you have decent teamates. kayle works especially good bottom lane with an aggressive laning partner like volibear caitlin or ash, but anyone who does decent dmg will do.
