Cosmogrand Zenith is a very solid creature, letting you build a board or buff one each time you cast two spells in a turn
You can start ramping as early as turn two with this guy, and the First Strike means youre less likely to have to trade him off to do so
An opponent who plays a Play with Fire in a Battle with a single defense counter will not destroy it, but trigger its transformation
He offers two keywords and +2/+2 to all of your Humans, provided you have four or more Humans in play
A sweet spot of two to three colours is a great place to start for your first attempt
In 60-card formats these alternate win cons can appear few and far between, but in Commander, where you have three opponents to distract each other and a larger card pool to choose from, they can thrive
