Shield Sweep - Hits an an AoE around him, kind of like whirlwind, but bigger radius, less damage

Meteor Kick - (See finishing move against Batroc in opening Ship scene from Winter Soldier) make it 10-15% Vitality finishing move, kind of like Hawkeyes stuff.

Airborne Assault - Leap that does a ground slam where you land. Smaller radius than Tactical Retreat (Huntsman), but he shield slams when he lands and does damage in a small area, larger than a touch spell, but smaller than whirlwind?

He gets to wield Thor's Hammer in endgame and imo is probably one of his more iconic sequences in the comics, so i'd watch the scene where he fights Thanos with the Hammer in Endgame, and draw some inspiration from some Aero type spells that involve using the hammer. You could even make a couple of combo skills where if you throw your hammer first, you can then shield toss them for a stun, or if you throw the shield first and then you throw the hammer at them they take bonus Aero damage.

Get hero tag by the way. :)
