All common cube.
Hi, and welcome to my cube. I'm still hewing this cube out of the marble of commons. Archetypes are constantly being updated, but in general this is what the colours are doing.
White: Make the tokens, play efficient creatures, non-creature spells are generally stuff like Pacifism and Kor Chant. Hoping for more good equipment.
Blue: Looters, fliers, lots of card selection and counters. Draw spells = good?
Black: Lots of 2 for 1 creatures, a decent amount of shadow creatures and some chunky creatures. Lots of creative ways to kill creatures and bring creatures back from the dead. Some Madness and sacrifice synergies.
Red: Zoom, zoom. Go fast. Lots of burn. Some discard and token stuff.
Green: Lots of good creatures. Several big creatures. Mana ramp. Some pump spells, and no problem colour fixing.
Artifacts: Equipment, train?, signets.
Multicolour: Generally cards which support the two colour themes and a bunch of staple spells.
Lands: Lots of fixing so you can play what ever combination, plus Desert for good measure.
