Welcome to the forum.
We're more into the "International Standard" decks here - 52 cards, four suits, thirteen values, plus one or more jokers.
Feel free to post about your deck if you like - but use the Conversation Parlor board.
I would shorten the video considerably - I only got halfway through before I lost interest. Keep it brief and fun. Think of a television ad; most are either 30 or 15 seconds. Leave out the cheesy bouncing letters at the start and you're well on your way to shaving down the video runtime.
I get that you're still in the concept phase, but the cards as presented in the video look really unpolished and unfinished. It's easy tp print up something that has a slightly more finished look to it. Impressing people visually will go a long way toward helping sell your concept.
