How about some Trickster cards?

[PhantomFox]

I was wondering if it would be possible to come up with 'trickster' cards.  Cards that fooled with people's mind or perception.  I'm not sure how many of these are technically possible though.  For example...

Darkness: Cloak of Shadow - X darkness

The next Y creatures to be played by the owner will be cloaked.  Cloaked cards' identity, power, health, and abilities can not be viewed by the opponent for Z turns.

Or...

Fire: Mirage - X Fire

Sacrifice a creature to create two exact copies of it: one real and one illusion.  The illusion card appears to be the same as the real one, but is in reality a 0/1 creature with no abilities.

Entropy: Kitsune Trickster - X Entropy
1/4
The Kitsune comes into play disguised as a random (but often powerful) creature from the element of your mark.  When killed, the Kitsune instead escapes back into your hand.

Death: Living bomb - X Death
Play on a creature. When killed, that creature will explode causing Y unblockable damage to your opponent.  (Buff might be invisible to opponent)

I might come up with a few later, and the other ideas I had didn't really fit this theme of deception.

Needs a bit of balancing, but it's not a bad idea IMO.

[Piter De Vries]

If possible (not sure) in Elements, those are good ideas (i wonder why no one thought about them before?).
There is a little problem, still: each card played in Elements is seen. So... opponent would know that one of the 2 cards is an illu', just not which one. With living bomb, if the buff is invisible, opponent would still know that one of the creatures has it, just not precisely which one.
And the problem with Kitsune Trickster is, if your opponent watch carefully at your quanta, he'll know it's not a powerful creature. Oh well, this may be not a problem.

I like the idea anyway, but not sure Zanzarino does / can apply it.

All the "concepts" are good, but making the AI not understand what is going on with those, especially on its own side, may be a hardtack.

[YoYoBro]

Well, i agree with piter that these cards may require quite a bit of coding but...

[PhantomFox]

Came up with one more 'trickster' card and a couple other ideas.

Delusions of grandeur - 3 Light
Give one creature +2/+2 and the rest of your creatures the appearance of the same buff.

Other random ideas:

Stability - 3 Earth
Target player has all their quanta evenly redistributed among all elements.

Spectre - 4 Death
Target Creature will survive one turn after reaching 0 HP.

Dense Forest  (Perm) - 5 Life
Hide: (2 life) May make any one creature (at a time) immune to attacks but also unable to attack

[YoYoBro]

I like all your ideas but stabilty which would kill any deck based, say, on massing quanta (fire lance, mono dark and such) or heavily penalize duos... and you should also make a light card which "reveals illusions"...

[PhantomFox]

Okay then, I had considered that.  So the best solution for stability would be to make it only self-targetable.  Or make the cost insanely high, but I prefer the former solution over the latter.

[YoYoBro]

Or just change the effect... maybe something like:

Sandstorm

The target loses 5 mana per element and gains earth mana equal to the total mana lost.
