If this was a release tied to an RPG or a comic book or a board game, I'd say, "Fantastic!" As a standalone, it's not going to have strong legs in a market this diverse.
Consider remaking the concept as an art deck - a real art deck. Use standard suits, first of all - using non-standard suits with no other merchandise to support it is putting two strikes against your concept to start with. Make the art take up the WHOLE CARD, put indices on as "flags" over the art, and use the titles and flavor text in a smallish banner at the bottom of the card.
To give you an idea of what I'm thinking of, look up Anne Stokes. She's done two Bicycle decks on her own and two Bicycle decks (plus a handful of others) for the Alchemy store chain. Look at her Bicycle decks. Big art that takes up the whole card, no titling at all, indices on top of the art. She even managed with the "Dark Hearts" deck to theme the deck by suit to some degree without actually bothering to label it as such - spades are death/skeletons, another of the suits was sylvan-themed, etc. Granted, her art a few ranks above what you have here, but there's nothing stopping you from upping your game with your artists.
BTW: consider ditching the name. It's a little too generic. A Google search for "Cross Realms" has a Chicago-based IT company as the first hit, the next three hits are about Worlds of Warcraft, and the fifth hit is about a future-setting RPG that had a "successful" Kickstarter project (it raised a whopping $100, had a single update since funding in August and was supposedly delivered over a month ago). Not the kind of company you probably want associated with your concept...plus your page on Facebook isn't even in the first FIVE PAGES of links, so the name's not helping you one bit in terms of search engine optimization. Might as well call it "Milk" or "Bacon"...
Alternately, ditch all this advice and make an RPG or a CCG out of this. You'll have marginally better odds, I'd think, and then you can make a deck based on THAT!
