What The Ur-Dragon actually does
Read off the card by the same engine the Forge and Analyzer use — this is the mechanical classification, not a summary.

What a The Ur-Dragon deck wants
The plan the Forge derives for this commander: the roles it fills and how many of each.
- 4× Evasion that does NOT target or attach — for a commander your own auras and equipment cannot legally touch
- 16× A cheap spell of any kind — casts per turn are the engine for an unrestricted cast trigger
- 16× A creature that HAS the keyword the commander's trigger counts — a card that merely says the word is not one
- 14× Expensive on paper, cheap to actually cast — the flip payoff for a mana-value damage trigger
- 10× Make creature tokens — a static anthem or a go-wide commander needs a board to be wide
- 26× A body of the exact type the commander's trigger requires — the wrong type is worthless here regardless of quality
- 5× Actually remove one problem permanent — preventing its damage is not removing it
- 1× Answer a whole board at once
- 2× Answer a spell or ability before it resolves
