Battlegrace Angel

Battlegrace Angel could cause a creature to have multiple instances of lifelink. For example, a creature you control that already has lifelink could attack alone while you control Battlegrace Angel, or a creature you control could attack alone while you control more than one Battlegrace Angel. If a creature has multiple instances of lifelink, they are redundant. You’ll still only gain life equal to the damage dealt.

In a Two-Headed Giant game, a creature “attacks alone” if it’s the only creature declared as an attacker by your entire team. If you control that attacking creature, your exalted abilities will trigger but your teammate’s exalted abilities won’t.

Exalted bonuses last until end of turn. If an effect creates an additional combat phase during your turn, a creature that attacked alone during the first combat phase will still have its exalted bonuses in that new phase. If a creature attacks alone during the second combat phase, all your exalted abilities will trigger again.
