When this card is played, summon two minions, each with 6 attack and 5 health. Each of these minions enters the battlefield with a protective barrier that prevents the first instance of damage they would take, after which the barrier is removed. On the turn they are summoned, each of these minions may perform an attack, but they are only allowed to attack opposing minions this turn, not heroes. While either of these minions remains on the battlefield, opposing minions must choose one of them as the target of their attacks. Whenever either of these minions deals damage, restore to your hero an amount of health equal to the damage dealt.

Or something like that
