I have had a number of games in which the rainbow dragon failed to deliver the description. I would love to hear a detailed description of how the dragon deals damage. Has anyone else had this happen?
Do the keywords on the dragon add to the damage? Is it that it counts keywords from per card and not per keyword? Are some keywords missing?

As the card says:
Attack: 8N
Stock: +2N
N = # different keywords in hand

So, if you play it when there are no other keyword cards on hand, N=2 (Legend, Dragon)
If there is another Dragon on hand, still N=2 (it's not a different keyword).
If a random card like Militia is on hand next to it, N=3 (Legend, Dragon, Quick)
If a card like Fanatic is next to it, N=4 (Legend, Dragon, Holy, Barbarian)
(And it makes no difference whether your hand is filled with 7 Fanatics. In that case you'd rather have a Zealot ;-))

I hope these examples clarify the card.

This does clarify. Thank you very much. This game is a constant learning process and I appreciate all the advice and help.
