Knight of Dawn's Light

2022-09-09 Each creature with lifelink dealing combat damage causes a separate life-gaining event. For example, if two creatures you control with lifelink deal combat damage at the same time, Knight of Dawn's Light's second ability will apply to those two events separately. However, if a single creature you control with lifelink deals combat damage to multiple creatures, players, and/or planeswalkers at the same time (perhaps because it has trample or was blocked by more than one creature), the ability will apply only once.
2022-09-09 If you control two Knight of Dawn's Lights and you would gain life, you gain that much life plus 2. A third Knight of Dawn's Light has you gain that much life plus 3, and so on.
2022-09-09 In a Two-Headed Giant game, life gained by your teammate won't cause Knight of Dawn's Light's second ability to apply, even though it will cause your team's life total to increase.
2022-09-09 The middle ability of Knight of Dawn's Light applies just once to each life-gaining event, no matter how much life is gained. If you gain an amount of life "for each" of something or "equal to the number" of something, that life is gained as one event and the ability of Knight of Dawn's Light applies only once.
