I think both are valid! GK generally exists to place Necrovalley and maintain it. The line between GK and stun tends to be the end goal and playstyle. GK is more centered around control rather than pure floodgating like Stun. Necrovalley on it's own is a very light floodgate versus most decks, so GK tends to focus on trades and preventing recovery. Stun is more about flat out prevention and making your hand as useless as possible. So Prinny's list falls into GK due to the focus on Necrovalley and trades with backrow rather than preventing action all together.
The general agreed upon bare minimum GK cardpool for something to be considered "GK" tends to be 3 Necrovalley 3 Commandant. I just like focusing more on the GK support even if it can be more of a brick at times.

Hi brother. Why is Tri-Brigade Arms Bucephalus II playing? can you summon it? I was also thinking about playing Change of Heart or Mind Control and super poly given that you are playing Garura.
The strategy is to steal the opponent's monsters to make powerful links.
In a previous deck list I saw that you put Underworld Goddess of the Closed World.
Do you prefer Scareclaw Tri-Heart? Super Starslayer TY-PHON can also strengthen the deck.
If you have recent replays, I would like to finish my GRAVEKEEPER'S deck so that it is optimal.

It's a rather old build, the replays have been replaced.
The general gameplan is to line up temples or royal tribute with necrovalley/a GK and basically just auto win from there. Most decks don't have outs to a spell version of fossil dyna.
If you were trying to optimize it, you'd basically just be trying to make it more consistent going first, or make it better going second. Priestess is there to help line up temples and royal tribute and the rest of the GK just do GK things (search necrovalley or make fusion)
Not really anything amazing to watch.
