Third Eye has another variant Twilight Sparkle cover up for the MLP Comic. This one ties in with the character specific mini-series that will be releasing alongside the usual set. Twilight Sparkle packaging up piles of variants definitely isn't an understatement when it comes to ponies I guess!
Third Eye currently has it up on Facebook, with no pre-order link. You might have to hit up their store for it for now.
Thanks ti Pierre for the heads up!
