Offer your opponent a handshake. If they accept your handshake, each player's Life Points become half the combined Life Points of both players. If you have "Unity" in your hand and show it to your opponent, they must accept the handshake.
Activate this card by targeting 1 Warrior-Type monster you control. It gains 1000 ATK. Monsters destroyed by battle with it are returned to the hand instead of going to the Graveyard. When that monster leaves the field, destroy this card.
