Darkness was my first pick when I started; not because it's 'cool', but because it sounded devious and flexible, and I like devious and flexible.
I was kind of disappointed with the element, however. There is too much 'teen-angst' and 'being dark is so cool' stuff in it, and not enough actual game-play-darkness.
Sure, Black Dragons look cool, vampirism is ever-so-popular with teenagers, Dusk Mantle is cool for being a Mantle and not just a shield, liquid shadow is oh-so-sexy-sounding, devourers are dreams-come-true for zerg fans, and twiligh - I mean, Eclipse is awesome for obvious reasons, but where are the really devious stuff?
Black Dragon is just a dragon... I hate dragons. They are big and massive and costly and don't have any special abilities - so totally out of place for Darkness.
Vampires and drain life... drain attack is an interesting concept, but does not provide new game-play styles; it's like the slightly interesting whipping cream on top of a bland, standard cake. I have only seen one actually interesting application of this so far: in a Vampire + Momentum + Adrenaline + Quintessence deck. (S)he lost the match, but I would have given the victory to him/her for being the only interesting vampire user around.
Dusk Mantle... I like the illustration, but how exactly is it different from Fog?
Liquid Shadow... usually used more as creature control and ability-replacement than for the vampirism. And there are so many other creature control and ability-replacement cards that are much, much better.
Gargoyle. Fits the theme, but not the game-play. It really does not belong here in Darkness at all.
The Devourer... now this one is actually unique in Elements, and keeps quite true to the element of Darkness. I will let this one go to the approved category =)
Nightmare is an awesome, awesome concept; unfortunately, it is not particularly usable yet, even with the HP drainage. Voodoo is absolutely awesome. Steal is my favourite card in the game.
Why are there so many massively (pun intended) out-of-place cards in Darkness, and so little cards that allow for unconventional, unexpected, totally devious ways to play the game?
Some examples:
- REVERSE attack and defence values on Nightfall. This actually makes Gargoyle fit, and does something other than giving a tiny little boost (boosting is not Darkness-style anyhow). Think of it as nocturnal creatures waking up and everyone else going to sleep
- hide your HP amount
- invisible spell-casting and land-placing
- hide number of lands and mana
- ability to add effect to a creature before summoning and hide the effect once summoned
- reshuffle and hide your opponent's hand from himself for a turn
- hide the remaining number of cards in the deck from your opponent
- choose a target for a spell, have your opponent choose a target, if you chose what (s)he chose, the spell has additional/stronger effect
- Drain HP based on the number of cards the opponent has in hand
- Drain HP based on the number of cards the opponent discards
- Force opponent to discard
- discard a random card from your opponent's hand
- discard a random card from your opponent's deck
- Switch creatures around on the field
- Cards that appear to the opponent as something other than what it actually is (i.e. actually make Cloak of Darkness do something OTHER than giving untargettability for three turns... that's a Cloak of Aether, not a Cloak of Darkness)
- Switch cards between your hand and the opponent's hand
- Reverse-steal (gifting useless cards to opponent, or simply to fill his field)
- Reverse-steal into opponent's hand
- temporarily reset minimum / maximum hand size for opponent
- trade your life for damage and vice versa
- allow your opponent to sacrifice something of yours, but the better the sacrifice, the bigger advantage you would get (mana + life?)
... etc.
And I'm sure there are much, much better ones, too.
The point is, Darkness was presented as the 'Master of Subtleness' in the account creation screen, but it really feels more like a rawr-look-at-my-massive-power sort of element. There is absolutely nothing subtle about big bad black dragons, or 3 turns of untargettability (regardless of how cool it looks or sounds, that's the only thing it actually does), or weaker fireball with an extra kick (drain) and weaker frogs with a kick (vampires), or a gargoyle with massive HP, or giving +1/+1 buffs.
Yes...
