Mashup of Citanul Hierophants and Sivitri Scarzam.

I got these ages ago and couldn't think of anything to do. A rare vanilla legend, plus a meta-mana-elf. What does that become?

And then I looked at the flavour text. A dragon-controller. Plus druids who secretly plan offensives. What does that give? A way to combine weenies into dragons!

It's strange that UB + G -> R, but it seems obvious. What colour overcommits to weenies? Red. What colour wants to cash in a lot of weenies to get a DRAGON? Red. There we go :)

I'm not sure about the cost. I could have made this match one of the existing card stats, but instead I just picked a size which seemed plausible. It may need to change.

Hee! I like where you ended up! And now that you explain it I can see the reasoning, though it wasn't obvious to me before that. Reminds me of Skirsdag High Priest. Tradewind Rider is the only card with an unrestricted "tap this and any two other creatures", and that gives a pretty powerful-when-repeated effect, so this actually seems fine. I love it.

Thank you!

Yeah, I was thinking of Skirsday High Priest too.

And yes, tapping that many creatures is quite hard. I nearly made it more general (eg. allowing multiple copies of the ability to activate, or not requiring this to ) but decided it was better to stick to the straightforward implementation.
