The two will likely be linked in the format, making cameos in each others decks and I think the existence of one makes the other better
White aggro has a much better time in Commander than red aggro for a number of reasons
Mix Atraxa, Grand Unifier, a multi-format all-star, with one of the most iconic video game villains of all time, and you have potential for a serious price tag
Certain cards like Fearow ("Genetic Apex") or Gyarados ex ("Mythical Island") can also burn away your opponent's energy
The card is ideal in older formats where there is an emphasis on lands and cheap spells, so expect to see the Vampire crop up in sideboards as a hate piece in Red
As nice as these are from a value perspective, however, youll likely not be pulling this deck apart
