Disclaimer: I will not focus on Art or grammar, unless the latter would make the deck too difficult to understand.
Well then! Not going to lie, my face when reading through the description of Lynda Simons was probably priceless, had anyone seen it. I was expecting someone obsessed with dinosaurs, but NOPE, MICROPLASTICS, SON!
I have to admit, I actually like the expanded Lash Out Against Losing options. Some things just require more description to make sense, and here it works out rather well. Not something I'd advise to do much, but Lynda pulls it off. Though with the oil well, could also have her inform everyone she's bought out the plot of land? For mechanics, Bahamut is scary, and I think the deck in general is honestly kinda neat for the idea with the sort of stupid/crazy awesome energy you don't often see!
For a bit of a longer thought train, I have to start my musings from the Simple Card Move that gives you a Black Gold Barrel for every Warrior in your grave. The deck as-is doesn't seem to have many Warriors for Plans to Win or Power Card Moves. However, if the Simple Card Move-created {Blockers} count, I'd have to suggest adding a maximum value to this. If the game goes on long enough, the amounts are going to become a bit much for a Simple Card move. It might feel too simple, but just "Gain 1 Black Barrel Gold" is perfectly valid for gimmick-based Simple Card Move. Maybe 2 if you have a Warrior there, or your opponent has a Warrior in Grave? Less swingy either way. Heck, an Invocation getting Black Barrel Gold for your opponent's grave would be pretty on-brand, or other Simple Moves using the resources for slightly more powerful effects?
Mechanically, another small clarifying question: Do Explosive Rocket Fists gain the effects cumulatively, but only once? So paying 3 Black Gold Barrels would {Strengthen} it only once?
Anyways, my bad for starting to ramble in this commend - good job!
