These are $1.27 a pack from the bots, and I love the Titans. Here are highlights of the packs I cracked and my status for this set of rares and mythic rares. I made some great pulls. I am looking to get as many of the Titans and Planeswalkers as possible to complete playsets.
Here is an Inferno Titan (and a Goblin Grenade, cool card!).
A Chandra's Phoenix.
An Acidic Slime.
A Sorin's Vengeance.
Sorin Markov (nice!).
A Day of Judgement.
An Angelic Destiny.
Here are the rares and mythic rares so far. I had bought a few of these before this booster rampage, especially two Grave Titans (my favorite card of the set).
