I know, when I saw your post I just freaked out; was just like "omg, why has this not come up before?! It's so obvious! :D"

But aye, although mine will include Knights as well, they're just one "family" the same as any monster group, rather than the primary focus. It's why I thought it'd be better to keep them separate, since your concept has such a different focal point and they both strive towards different styles of gameplay....really should draw up a Knight card or two, have been totally neglecting them.

Clockworks/Krogmo versions...aye, much better idea! :D I do like Clockworks version, since I've been quietly referring to the "field" as "Clockworks" anyways since that's where everyone would do battle! I was originally gong to call the Graveyard "Return to Haven" but felt that it didn't really work for when monsters got killed. Perhaps it'd be more appropriate for you?

I'm sure you could also fit Puppies in your version somewhere as well; I mean there's at least one LD map with puppies in it :D

(Do I sound like a child for my mind immediately thinking "Red/Blue Versions"? x3....)

Well akin to MTG itself I'll be drawing up various "revival" cards to pull certain cards back from the Graveyard, although the Undead family is the one that's going to be abusing the Graveyard the most, such as Phantoms who can be played from the Graveyard as if they were in your hand (simulating the SK Phantom effect of killing them and them just perpetually coming back no matter what you do), but for the most part, once a Character is killed/defeated, they'll be sent to the Graveyard and left there. Thus encouraging a larger army of characters and traps; I always like the feel of getting a big wall of creatures in front of your base ready to smash your opponent's face in :D

I saw your Arena card actually; really cool idea. Based on Yu-Gi-Oh uhmm....."Field" cards were they called? I can't remember exactly, but it had a similar effect, and totally skipped my mind. Should suit your style of gameplay really well with the duelling vibe.

UPDATEDIT:
Updated the OP so it's not only neater/more organised, but includes extra details, such as family playstyle themes, status descriptions etc.
Also added a pile of new card ideas (totalling 41 as of now) albeit a number of them lack flavour Art still, since I'm doing the text/background for some to get the ideas down, without needing to spend ages making art for it inbetween that and other ideas.
And finally have just gone over them all and added costs, stats, effects etc. Filled in all the details. Of course, will be going around and editing stuff here and there if I find any more flaws or balance issues.

I don't follow what you mean.

In case it's not clear, we're not trying to compete against each other or anything; we just both had drastically different ideas of what the concept would look like and decided to just share it as we saw it. We're still helping each other out and all, there's just no point trying to moosh both versions together when they're as different as they are or one of them would get completely swallowed up and lost.

If you meant something else, then I'm not sure, really o_o?

Trying to moosh them together would undoubtedly result in "fighting" of sorts, as our ideas oppose too much.
If we were to work together on any kind of SKTCG and make something as a team effort, the end result would either come out entirely as one of our ideas and not the others, or a third and altogether entirely new concept that has little/nothing to do with our originals.

Saying that, that's not necessarily a bad thing, considering that both of our ideas are heavily based on current TCGs. May not be such a terrible idea to concoct an entirely original concept for a TCG that isn't based heavily on existing games. Possibly would be the way to get more attention~

Personally, I'd be up for that, plotting out an original set of TCG rules based on SK game mechanics~

I've no idea; would depend on how it would run/play, what it'd be like etc. Few possible options of the top of my head of unique playstyles:

1/ One player plays a team of Knights, the other plays the "Clockworks" and on their field places traps, monsters etc in an attempt to defeat the Knights before [x] condition is met by them. Knights are stronger, have more gear etc, but have no respawnability and rely on spells/gear from the deck, while the CW player relies on spitting out as much as fast as possible.

B/ The player is the Knight themselves, and the deck is full of skills, gear, abilities etc and it essentially becomes a 1v1 match against each other, using the draws to execute various attacks or re-equip themselves.

3/ "Competitive Co-Op" where the two players play together, against each other: as a team, but technically compete against each other to achieve more. You'd throw Knights down and the card draws would be various monsters, traps, events etc you could summon to either fight your own Knights in order to achieve points, or to target your "ally"'s Knights in order to slow their knights down while you attain points. Could be various bonuses or effects for being higher, but close to your partners score (to encourage you to help their score as well) rather than just rocketting above it (for an arbitrary example: you can only slow them down if you're only 3 points higher, and can't do it if your'e 20).

Personally, I'm kinda digging /3 because I don't think there's another TCG out there even remotely like that. All TCGs are very predominantly "A versus B" and have an extremely "beat the other guy's brains out" vibe. SK is mostly a co-op game so quite like the notion of making a competitive co-op ruleset around working together, but still trying to do better.
Like when you play any co-op shooter and you're both working together to beat the level, but you can't help but wanting to make sure the level finishes with you having more kills/damage than your chum.
Rules would need to be considered/thought up more, but...it's pretty damn original I'd say :D

SOUND FUN?
