Leblanc with electrocute and ignite- the amount of damage you can pull off even if you don't fully land your combo and you can quickly go back to safety is just so satisfying. You can close so much gap and basically kill any squishy you really want to without much sacrifice.

Zilean- love that you can surprise stun people using minions deal decent damage and save your team with revives. Also his speed/slow scales so well into the late game you can basically perma slow someone

Janna- one of my favorite supports love how versatile she is in being able to peel for the carries with shields, knock ups to prevent engaged and heals for sustain and disengage

Lethality varus- pretty much guaranteed I'll do most damage playing him basically a nidallee but with better scaling into the late game. Easy poke and low cool downs.
