I have just 4 opponents to write up of the imposing list of 72 that sat before me way back when.
The current Arena opponent under the microscope is the mighty roc.
The roc actually made it in history at least as far as Noah's ark:
All feathered things yet ever knowne to men,
From the huge Rucke, unto the little Wren;
From Forrest, Fields, from Rivers and from Pons,
All that have webs, or cloven-footed ones;
To the Grand Arke, together friendly came,
Whose severall species were too long to name.
