Building a Lucario Vstar deck. Need some advice.

So as the title says I've been theory crafting a Lucario Vstar deck for fun (and to maybe take to my local comic shop to battle), and I think I've gotten something halfway decent built, but could use some tips.

Pokemon: 2 Riolu SVI 2 Lucario SWSH9 2 Lucario V SWSH10 2 Lucario Vstar SWSH214 1 Mew ex MEW 3 Gible PAR 3 Garchomp ex PAR 2 Koraidon SVP

Trainer: 3 Iono PAF 4 Irida SWSH10 1 Boss's Orders SWSH251 1 Prime Catcher TEF 3 Rare Candy PAF 3 Nest Ball PAF 4 Buddy-Buddy Poffin TEF 3 Ultra Ball PAF 3 Super Rod PAL 3 Rock Chestplate SVI

Energy: 1 Jet Energy PAL 14 Basic Fighting Energy SVE

One thing in particular I'm not sure of is if the two Koraidon ex is too redundant with three Garchomp ex also in the deck (my thought process was it'd be useful having a passive energy adder ability on the bench with Garchomp in the active zone to power up Lucario SWSH9 for a big hit). Any thoughts and suggestions would be much appreciated!
