treasure chest. I have eight packs of Scars of Mirrodin and four packs of Avacyn Restored. I bought some of these as retail packs from walmart. Some people prefer not to buy single packs this way because they sell for about a dollar more than you can get them at your local hobby store but I've found that there are actually better cards in these packs. Some of these also came from a big lot of miscellaneous sealed packs I bought from Troll and Toad online. Hopefully whoever wins these from treasure chest pulls will end up with some good cards. I hope you all get rares from these.
From the Scars of Mirrodin packs you could pull some pretty sweet cards. This series came out way back in October of 2010 so a lot of the rares have had time to rise in value. Some great cards worth looking out for are Koth of the Hammer, Myr Reservoir, Mox Opal, Venser the Sojourner, Elspeth Tirel and Sword of Body and Mind but there are many other great cards that are valued at $10 or more plus you will have lots of great cards to add to your playing deck and a great story to tell about how you got them.
Avacyn Restored came out in December 2012 so this series has already had some time to mature. Some cards you might be smiling to get are Tamiyo the Moon Sage, Temporal Mastery, Tibalt the Fiend-Blooded, Avacyn Angel of Hope and Sigarda Host of Herons. Of course there are many other great rares in this set but I won't try to name them all here. Lets just hope you get a lot of great cards when you open these and hopefully some of them will be foils.
Remember, if you want a chance to get these cards you will want to run world community grid on your computer. Download it here.
