I like the idea, but I think it might be better off implemented with modes, where it can summon another "blank" card with one of the keywords, for example:
Next card will be:
Mode1: Aqua
Mode2: Restoration
etc.
In that case, you might also want to make this card quick.

I disagree. I think it's fine as it is now. In most cases, the player would already have another of the keyword he wanted to take effect in hand without having this card draw one specifically.

But in it's current state it will be very powerful in combination with cards like Rainbow Dragon. The effect on the card is irrelevant since one could just as easily discard it instead.

I think Spoon is right. Think it combined with Rainbow Dragon. It would be devastating, it's automaticaly 40 damage and +10 stock!

Ah, I misunderstood. I thought you were proposing to have it stay as it is with several keywords but to summon another keyword card to play right after for the effect, which would be insanely powerful.

I didn't see any mention of removing the keywords in your suggestion. If that is what you're trying to propose, then I would agree.

I disagree. The whole point of this card is to chain it with that type of keyword. That would all be lost by the proposed change.
As for the argumentation: A rare - uncommon combo is allowed to kick ass. (Clay fabric - Pyramids, Darkforge - Orc regiment to name the first 2 that spring to mind...)

PS Rainbow Dragon feels kinda underused, I hardly see it around.

I use it in all my decks, and I can name a few other players I have seen using it against me
