I am thinking you may have misinterpreted the info on the page. Terra x Diamond always results in Quetzal, likely due to an oversight on TL's part. Similarly Aqua x Diamond always results in Mercury, and, although untested, Ignis x Diamond most likely always results in Crusader. The Elemental Type's special breeding qualities are outlined on the Aqua Dragon and Terra Dragon pages.

As for in the arena, everything I've read/been told is that the Dark, Elemental, and Tarot types have no advantages or disadvantages in the arena. If a pure Elemental or Tarot type were to exist in the arena, they should be treated just like one would treat one of the corrupt dragons (except Corrupt Stalwart and Corrupt Artifact), or an Olympus Dragon, to a lesser extent.
