How The Ur-Dragon decks play in EDH
The Ur-Dragon is a five-colour commander in white, blue, black, red and green costing 4WUBRG, and its legendary creature - dragon avatar line shapes the whole deck around it. It draws extra cards, so the deck can afford a lower curve and lean on volume. Built-in evasion means damage gets through reliably, so effects that scale that damage are worth more than extra bodies. The cards below are the ones The Ur-Dragon decks actually play most often, grouped by the job they do.
