Heroine and I played our games, she won the first match as Zelda against my Palutena on Omega Living Room (Nintendogs stage). That was an extremely close game, with the timer having less than one minute remaining when we finished and us both at very high percents.
The second game was a Rosalina & Luma mirror match on Omega Rainbow Road. I dominated and didn't lose a stock, but it got confusing at times due to the fact that not only were our character palette swaps similar (Purple and Pink), our Lumas insisted on spawning as the same colour as each other several times.
The last game was on Final Destination (Omega?), with me remaining as Rosalina & Luma and Heroine switching back to Zelda. This game was not NEARLY as one-sided as the previous match, quite intense really. I won in the end, so the final result is 2-1 in my favour. Fantastic games, for sure.
I believe it's worth noting that we played more games together afterwards for fun and did another Rosalina & Luma mirror match. I lost and it was a much closer game than the one we played for the tourney. I wouldn't blame Heroine for letting the nerves get to her head and would have benefited getting a warm-up with Rosalina.
