A good all round card that fits quite nicely into the archetype although probably in a removal/disruption slot rather than anything else
Though, Sorin, the character, is a Vampire in addition to being a Planeswalker, so I guess I didn't really color too far outside the lines here
Ravager Wurm can not only get in for a big attack, but adds some removal to the mix
And, while were on the subject of ludo-narrative dissonance,* what the entire library and summoned creatures are** is a bit hazy and unintuitive, but a bit of thematic weakness isnt a bad thing if the gameplay and flavor fit well
These can be tapped to add colorless mana, but can only cast artifact spells
Flamebreak is the most bang for your mana buck, which is why its harder to cast with three red pips
