Oh wow, completely mised this one - big thanks for the win!
For our next challenge, I didn't really have an instant inspiration for something new - and since I definitely don't want to delay this contest any further, I decided to roll one of my already existing challenges instead (together with the usual two completely random ones, of course). And this leaves us with..:
LIMIT #92: Drive around! Your card is a Vehicle, cares or interacts with them. (Thanks, Daij_Djan!)
LIMIT #131: I don't ike this. Your card is better against specific cards, decks or archetypes. (Thanks Flo00!)
LIMIT #140: The Tour de France - your card has a cycling ability or cares about cycling! (Thanks, thaneofglamis!)
Fuelage Saboteur Creature - Zombie Pilot Whenever a Vehicle becomes a creature, put a -1/-1 counter on it. When you cycle ~, you may put a -1/-1 counter on target artifact. Cycling (, Discard this card: Draw a card.) 2/1
