I like the design of these new colour hosers a whole lot more than just slapping protection on middling creatures.
I'm not sold on the 3/1 fear for 3 when your opponent isn't in at green or white. It feels subpar enough to be one of the random hosers, which can swing one matchup, but do nothing against the rest. I'm interested in seeing how he plays though.
Edit: This is mainly for cube, I think he'll see play in standard
