I'd say that regardless of the visual similarities, they are 2 very different cards..
I hope you are joking because they are very similar. I'm sure that the first reaction of everyone would be that they are the same card, only different element, kind of like belonging to the same "set".
That wouldn't be a problem if posting card ideas the normal way, but it is a problem in a card idea competition like this one. That the key here. In card idea competitions, all ideas must be clearly unique.
If I understand correctly, in your idea, the card goes on top of the deck and then you draw it, so it's basically like it goes to your hand, right?
Do you consider Congeal and Basilisk Blood Very Similar? Enough that the other should not bother existing because of the first? Regardless of Similarity of the 2 cards and my non-acknowledgement of twinbusters card before publishing mine, I don't believe mine should not have the right to exist. People should be choosing between the ideas to find the best for the game.
Congeal and Basilisk Blood are cards made by Zanz so they play no part in this.
These two ideas here are posted for the same
card idea competition, posted almost at the same time, and are almost identical. Like I said, when we are talking about card competitions, rules are different then when we would post card ideas in the "Card Ideas" section.
And you not knowing about twinbusters card idea makes no difference what so ever. "I didn't know" does not hold in real-life court nor does it here. The fact is that twinbuster posted his idea first and that's all there is to it.
In situations like this it's recommended that the person who was 2nd (that's you) accepts "defeat" and tweaks his/her idea so that it's
clearly different. That's the honorable thing to do, and I suggest you start thinking of ways to tweak it.
If we allowed your idea, I could simply take any idea on this topic, change it a bit, and then post it as my own.
