Only since the release of Crimson Vow, I have noticed that sometimes Blizzard Brawl does not recognize that three snow permanents are present on the battlefield, therefore not giving indestructible to my target creature.

In the attached screenshots (and hopefully the logs), a Blizzard Brawl and Vengeful Reaper can be seen in my graveyard and my lands are snow lands. I used Blizzard Brawl to have my Vengeful Reaper fight a Righteous Valkyrie. The Righteous Valkyrie killed my Vengeful Reaper because Vengeful Reaper didn't gain indestructible from Blizzard Brawl.

This has cost me a few games this past week, so I'd really appreciate a fix soon. Is this a known bug?

Thanks!
