Sephiroth, The Hero

If Masamune is equipped to Sephiroth he gains 2/2.

At the beginning of your end step, you may sacrifice an artifact, creature, enchantment, land,
or planeswalker. If you do, each opponent may sacrifice a permanent of their choice that shares
a card type with it. For each opponent who doesn’t, that player loses 2 life and you draw a card.

"Now beg for your lives."
