Fractured Bond

Broken Trust: When Fractured Bond enters the battlefield, choose two target creatures you control. They each gain +2/+0 and "This creature attacks each combat if able."
Lingering Affection: Whenever one of the chosen creatures deals combat damage to the other, you gain life equal to that creature’s toughness, and draw a card.
Love and Hate: If one of the chosen creatures dies, the other gets +3/+3 and gains lifelink until end of turn.
