Success speaks for itself. How many people were there? What was the idea behind the scepters (a controllish build?)? Why no mages? I'd love to know what you were thinking.
I chose the red splash over black or white because i felt that it had the least amount of dead cards (2 pyroclasms vs. any amount of targeted removal in builds with other colors). I also thought that pyroclasm was a better way to win vs. goblins than relying on mongoose/ worship (ironically goblins was the only deck that beat me). You have access to reb for anything with counterspells or high tides. And finally, although white gives you meddling mage and black gives you confidant, legacy is big on creature removal, and those guys are really easy to kill. That's also one of the reason for the scepters- aside from being amazing, they're also a strong alternate win condition.
As for the 1-ofs: I've read all the decklists but I'm not all that familiar with legacy in general. It seemed smart to have access to a bounce spell, a wish for extra utility, and a removal spell that does more than 2 damage. The mystical would have been merchant scroll #2 if it were able to find pyroclasm. Psi blast was amazing every time I drew it. I would probably go up to 2 if I were to play the deck again.
the sideboard was:
2 tormod's crypt
2 artifact mutation
2 pyroclasm
3 stifle
3 reb
1 FoF
1 berserk
1 echoing truth
I would also cut the wish and add in the second echoing truth md. Which means you can cut the berserk and fof from the board. Maybe a 3rd scepter belongs there. Overall, I think this deck is very powerful although not completely tuned. I hope some ppl will decide to break out the dryads for columbus.
