Sephiroth, One-Winged Angel Legendary Creature Angel Nightmare Avatar Flying Super Nova As this creature transforms into Sephiroth, One-Winged Angel, you get an emblem with "Whenever a creature dies, target opponent loses 1 life and you gain 1 life." Whenever Sephiroth attacks, you may sacrifice any number of other creatures
Jaxis, the Troublemaker This troublemaker is incredibly valuable
This one-drop equipment equips for one, gives the equipped dork a boost of +1/-1 and when it dies you draw two cards
This allows decks to have the flexibility to solve problems they couldn't naturally solve and have reach they wouldn't usually have without having to sacrifice much to get it
