So Ant, you are trying improve the game, and not me? If I dont want a card I dislike being alive, or Im trying to get people voting to a card I like the most, Im trying to improve the game, the way I think its improved. And its false that I always have negative comments. No offense taken, but dont think my comments, even the negative ones, are to make the game worse.
Card Curator, now that I know when the poll resets, I realize that still this way the old options got votes from people that didnt even see the more recent ones. I dont think its fair, and maybe we should think about another way to do this.
That said, I will comment then, what I think about the old options:
Pony: I like the mount series idea, but this card is simply too weak. Of course, we are giving a creature control card to all elements, and some like light dont have it until now (ok, light can kill death or darkness creatures, lol), but I dont really see it being used, because its too weak. 3 random quanta for 1 damage? Of course, other weapons are already weaker than elements weapons.
Shard of Restraint: yes, if the point was having a shard trinity, it wont get real anymore. The skill was choosen considering the fact that previous shards had a skill that was related to life points, but this is also no more true. So I think the new shard recently added removes a lot of the appeal this one would have. And that said, the theme doesnt feel correct, I wouldnt like this skill being avaliable to all elements from start (maybe it could be, but then Death or Fire could have it in a more powerfull form before). And, too weak to a rare + 1500 gold. The skill is interesting, but not the card at all. If this get approved, I would suggest a poll about making it normal creature instead of shard.
Yin Yang: another very weak card. I already dont like the fact that this would add one more card to my deck, with an effect that is not that powerfull, but the variable cost totally kills it. Look: if the creature attack and HP are next to each other, the card is almost useless. So you should give the creature more attack, or more HP, with a bigger gap between them. If creature is yours, you will usually want more attack. I was thinking about a 30/2 Elite Armaggio, but wait, it will cost 30 gravity quanta??? No way. How about use on enemy creatures? It would really hurt that Ruby Dragon... but to do so you need fire quanta... and remove the dragon with a spell like Shockwave, or Drain Life, or Fire / Ice Bolt is even better. With that variable cost, the card has almost completely no use. And, does the Yin Yang really fits for this theme?
Pigley is by far the most powerfull one. In fact, totally OP. For 5 quanta (you can have in 1st turn with 2 quanta towers), you will double the cost for all in opponent hand? And there is a point I dont know if its solved already (Im too lazy to search): if the opponent have 7 cards in hand, it will become an 8th card, in your turn. So will this prevent the opponent to draw its card? In fact, I like the idea about a serie of cards that are like trojan horses to your enemy, but 1) tooooooo OP 2) we can have one for each element, in this case, but really a that powerfull one in Other? Maybe other could have no trojan horse, lol.
That said, if I had to choose among these 4 only... hmmm... Looks like I would go for Pony. The serie idea is good, and if its weak, that can be changed a bit, maybe increasing the attack. Pigley serie is fun, but these tricks dont fit to Other in my concept. The Shard would receive my vote if it was in a element related to its skill theme. Yin Yang looks like a dead card.
