MPDC League: Silverblack Tribal Rules

This week the MPDC League switches to the Silverblack Tribal format! Once upon a time, Tribal was actually an official format on Magic Online, existing in both a Standard and Classic variants. This format is all about creature combat, emphasizing a particular sub-type of creature to create what is essentially a theme deck of that particular sub-type. Traditionally, the rules for the Tribal format were as follows:

1. One third of the total cards in your deck must share a single creature type. Technically this does include non-creature permanents that have a creature type (although no such cards are currently in Standard). Also, "Artifact Creature" is NOT a creature type, as Artifact is a card type, not a creature type.
2. No Sideboard is allowed.

 For the MPDC League, both of rules will be in effect. Two additional rules exist:

1. All cards must be either Commons or Uncommons that are currently in the Standard set.
2. Your chosen creature type cannot be "Human" (although you can include Humans that share a different creature type instead).

And just as before, there are currently no cards banned for the MPDC League.
