Wait a second: Let's say i decide to make a spell with the spaceship card, ok? Then i choose these requirements:
# If the card is a creature, it must have a passive skill. (Example: Airborne, Poisonous, Voodoo, Obsession)
# If the card is a creature, it must have a equivalent stats to a creature already in its element. (Example: If it's a Gravity creature, it could have stats of 0|3 like the Otyugh, or 2|30 like the Elite Armagio. If it's a Time creature, it could have stats like Deja Vu with 1|1, etc.)
# If the card is a creature, it MUST have an active ability of the opposite element. (Examples: Steam Machine, Anubis)
# If the card is a permanent, it must have an activated ability. (Examples: Golden Hourglass, Pulverizer, Trident, Trebuchet, Mindgate)
# If the card is a permanent, it must have some form of 'counters' or a timed duration to it. (Examples: Bone Wall, Sundial, Hope, Wings, Phase Shield, Cloak)
I can fit all 5 requirements and yet do any card of my choice, as long as it's a spell! Or did I miss something in the wording?
