Olivia Voldaren wasn’t what we expected when we thought there would be a Red and Black Legendary Vampire; we assumed it would be a high costed but decent General for Commander. Instead, we got a very good mythic rare that may see Standard play. As the picture is rather low quality, I’ll post what she does here:
Olivia Voldaren
Legendary Creature – Vampire
Mythic Rare
1R: Olivia Voldaren deals 1 damage to another target creature. That creature becomes a Vampire in addition to its other types. Put a +1/+1 counter on Olivia Voldaren.
3BB: Gain control of target Vampire for as long as you control Olivia  Voldaren.

She’s a very good card, namely for her first ability, giving you a consistent way to kill opponent’s creatures and boosting herself in the process. If you really want to, you can always hit a creature and then take it over with her second ability, or just take control of opponent’s vampires in the mirror match. Being a flyer is always a plus here.

So, all in all, it’s a great card, and I hope the rest of Innistrad is as good as they’ve shown us so far.
