They all cost three mana.
Printing planeswalkers this cheap is a very dangerous game. Sometimes it works out fine and you end up with Chandra, Acolyte of Flame, Jace Beleren or Ajani, Caller of the Pride – perfectly reasonable planeswalkers. But sometimes, you end up with Oko or T3feri ruining multiple formats.
Where does the new Ob Nixilis rank? We’ll find out in a few days, but I already have a feeling that he is going to shape up Standard.
Ob Nixilis will change the way we build our Standard decks. If you’re playing a control deck, you’ll have to find a cheap way to get rid of not one, but two cheap planeswalkers tearing your hand apart or dwindling your life total starting on turn three. Creature decks will need to find ways to consistently be able to attack it through an army of Devil tokens to keep it off the board.
But how should you build your own Ob Nixilis deck?
The first ability essentially makes your opponent discard a card unless they pay two life, which is going to be the case for most of the game until they start either getting too low on life or their hand is empty. In a format like Historic, this can even backfire against a deck like Grixis Phoenix, but in Standard, this is a very powerful ability. 99 percent of the time your opponent will be paying the two life early on, unless you just randomly stumbled against a Reanimator deck.
This means that we want to build our deck as aggressively as possible to really take advantage of our opponent taking a bunch of damage every turn. I say bunch because we will be using the “casualty” option on Ob Nixilis almost every time we get the chance. It’s one thing trying to fight off a planeswalkers on turn three; it’s a completely different thing trying to fight off two of them.
