EDIT: as for the size limitations, do they have to be no larger than 282x436px or no smaller than? Or even both?
Can we post more than 2 images?
Would it be possible to have, for example, a redone Golden Hourglass and a redone Ray of Light and meet the conditions with that?
It's not a bigger than or smaller than requirement. It has to be those exact dimensions.
Please don't post more than 3 images(one element, second element, first or second element upgraded). But you can change those three images as much as you like until the countdown ends.
I don't understand what you mean. Golden hourglass is a Time permanent, and Ray of Light is a Light Creature. That meets the requirements specifically.
EDIT2: I understand what you mean now, and no, that would not meet the requirements since you'd only have two images. You'd need to show an unupgraded Light card then.
EDIT: I updated the rules so now it's a requirement to post it in the Card Art section and provide a link to it in this topic.
