This is a new design idea for me. Onslaught block was probably my favourite draft format due to the tribal feel (Not because of mashing 2/2 morphs into each other) and I wanted to replicate that feel in a tribal cube.
I wanted a cube with a huge Creature:Spell ratio so it really feels like a tribal clash. I have a large degree of Changeling and Shapeshifter creatures scattered across all five colours to further enable tribal synergy.
Cube Size: 500 Cards
Breakdown: 80 Each Color, 34 Colorless/Artifacts, 26 Multicolor, 40 Lands
I recognize that my mana fixing is not tier one, and this is because I wanted this cube to be more budget friendly than my main cube. It will become more apparent the more we test whether the ability to play Allies or Slivers is severely compromised due to poor fixing.
Any feedback is greatly appreciated! This is my initial draft and I have not run it by anyone, so any criticisms, changes, and comments are welcome.
