Tiamat is a dragon. Tiamat is immune to offensive psionic power cards, offensive blood ability cards, and offensive unarmed combat cards as well as the offensive psionic power and offensive blood ability of opposing champions. Any dragon champion of Tiamat's player that is defeated in battle is returned to the pool with attachments, instead of being discarded (or sent to the Abyss or Void). This makes Tiamat a good choice for a dragon combat deck.
Tiamat may not be played if you already have an avatar in your pool, and so long as Tiamat is still in play you may not play another avatar. Although Tiamat is a solid avatar, you are much more likely to encounter the Celestial Emperor when facing dragon decks. If you are playing a dragon deck and expect to play against one then this avatar may be a good choice to avoid a Rule of the Cosmos problem.
