Dynaheir is a Commander eligible in a beloved three-color combo that has Blue for counters and card flow, Red and White for removal like Chaos Warp and Wrath of God, and then loads of good stuff like Cyclonic Rift and Esper Sentinel and ramp like Land Tax and Smothering Tithe

I have not even bothered to list things like Wild Mongrel from last year and Exalted Angel from this one as they simply no longer have any cube relevance
