Magic The Gathering Cards of types 'Avatar' and 'Soldier'

Vigilance (Attacking doesn't cause this creature to tap.) When Sephiroth enters, creatures your opponents control get -2/-2 until end of turn. Whenever a creature an opponent controls dies, put a +1/+1 counter on Sephiroth.

Jenova Cells - Whenever Sephiroth attacks, you may put a cell counter on target creature. Until end of turn, each modified creature you control has base power and toughness 7/5. (Equipment, Auras you control, and counters are modifications.) The Reunion - {3}, Sacrifice a modified creature: Return this card from your graveyard to the battlefield tapped.

Whenever Sephiroth enters or attacks, you may sacrifice another creature. If you do, draw a card. Whenever another creature dies, target opponent loses 1 life and you gain 1 life. If this is the fourth time this ability has resolved this turn, transform Sephiroth.
