Quote from bravelion83 »A reminder to everyone:
In the MCC, putting rarity on cards is mandatory! If you don't put a rarity on your card, expect huge deductions in both Viability AND Quality.
Also, you should format your text cards accordingly to the forum rules (see the "this formatting looks best" spoiler in the linked OP). Again, expect deductions in Quality otherwise.
