Leyline of Hope

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, Leyline of Hope's second ability will apply to those two events separately. However, if a single creature you control with lifelink deals combat damage to multiple permanents and/or players at the same time (perhaps because it has trample or was blocked by more than one creature), the ability will apply only once.

Because damage remains marked on creatures until the damage is removed as the turn ends, nonlethal damage dealt to creatures you control may become lethal if Leyline of Hope leaves the battlefield or if your life total drops below 7 life more than your starting life total.

A player's "opening hand" is the hand of cards the player has after all players have taken mulligans. If players have any cards in hand that allow actions to be taken with them from a player's opening hand, the starting player takes all such actions first in any order, followed by each other player in turn order. Then the first turn begins.
