February 7 and 8, 2013: bought three packs and paid $10 to the bots for many RTR cards (the cheaper ones). Nice Pulls!!!
These are the cards I am missing.
Return to Ravnica
and Limited Edition Alpha (just kidding, I will never own these cards!!!)
As of February 18, 2013, these are the cards I can buy while they are in Standard from Innistrad and Dark Ascension:
kessig wolf run
past in flames
mikaeus, the lunarch
essence of the wild
beguiler of wills
flayer of the hatebound
March 31, 2013 update: paid $22 to the bots to buy all of the cards in the above list, and added three packs of Avacyn Restored. Latter were a great addition: two more cards added (Zealous Conscripts and Angel of Glory's Rise). Here is one of the packs.
May 1, 2013 update: 2 packs of RTR, and 2 packs of GTC. I recently bought a few miracles to feed my Crackling Perimeter deck. Here is what I am missing for AVR.
The packs for RTR. Pulled an Abrupt Decay!
What I am missing for RTR.
And the GTC packs. I am missing many of GTC because I plan to buy many more packs before I buy singles from the bots of the cards that I am missing.
Pulled a Mythic Rare!
May 5, 2013: added 2 packs of RTR and 2 of GTC. Pulled a Supreme Verdict and an Aurelia!
...and I am loving the difference between ISD block completion and RTR block completion. For all of $5 I got almost every rare, uncommon, and common in Gatecrash! I am missing all of 21 cards.
These are the AVR cards I can buy before they rotate out of Standard.
Tyrant of Discord
And these are the ones for RTR.
And now that I am only missing a few of GTC, these are the ones I can get while in Standard.
