[Kagero/Nova Grappler] The Return of Mr Overlord!

[Draxzorion]

G0:
SV: Evolving Reincarnation Miraioh
4 Beast Deity Heal
8 Stand (4 Being Beast Deity)
4 Beast Deity Draw

G1:
4 Beast Deity Solar Falcon
4 Clay Doll Mechanic
4 Energy Charger
2 Dragonic Gaias

G2:
4 Hungry Dumpty
3 Beast Deity Golden Anglet
2 Beast Deity Brainie Babio
2 Street Bouncer

G3:
4 Mr Invincible
4 Original Dragonic Overlord

The Main Goal

~Use Mr Invincible's skill to unflip a damage each turn and with the help of hungry Dumpty and Clay Doll you can spam Dragonic Overlord's skill to gain 5,000 power and if it hits a rearguard you can restand it.~

Why Energy Charger and Dragonic Gaias?
Energy Charger is here to utilize Mr Invincible's soul charge skill to make the deck a bit more consistent, while Dragonic Gaias is in as tech. Gaias skill lets me SB 2 and rest it, and give a kagero unit in the same column as it +1 critical. As the deck lacks critical triggers, Gaias gives the deck the potential to deal some extra damage, If they guard their rearguard when Overlord attacks for 16k and +1 crit, I still have a chance to drive check a stand and continue it again.

Beast Deity Anglet & Babio and Street Bouncer
Beast Deities, With 21 Beast Deities in the deck, there's a high chance to get a Beast Deity in the damage, So why not tech in Babio, when it hits I can cb1 and restand a Beast Deity unit, the CB used is easily mitigated by Mr Invincible, Anglet if it restands it gets +3,000 so it can be used with Babio and Stand Triggers. Street Bouncer is just there for draw power if needed as a tech.

Gaias' ability is during one attack only.  It's pretty worthless for this scenario you're listing.

Tri-stinger has the more reliable unflip engine in my opinion, and the Aqua Force units have significantly more synergy with this tactic.

I would forego the draw triggers, since checking a stand with Overlord is your win condition.

This deck reminds me of that awesome episode in the first season with kai vs kamui

I personally think that you should change your starting vg to beast deity riot horn since you prioritise in stand triggers.
And here are some useful cards :
for g 1:
tip:
you might want to have only 2 energy chargers since its skill reguires 2 soul blasts and riding to g 3 means you have only 2 cards in soul. its kind of useless once you've used up the soul so i recommend either one of these cards to replace some of it:

Beast Deity Max Beat: since i've already said it you prioritise in stands so this one is a good one.

if you have a useless card in your hand  you could add shout or beast deity herarti destroyer to replace it.

I added glows to either the cards or the grades
g2: you could add a marvelous heni if you want. though not alll that good its also not that bad. getting four rgs is not a hard thing to achieve.
but all this is just my personal preference though i recommend you to use the
raizers since there is a lot of cards you can pick from and all their skills are obviously worth the try.
Nothing to say about the g3s though.
