Living Lore

You may cast a sorcery this way even if it's not your turn.

If you cast a spell "without paying its mana cost," you can't choose to cast it for any alternative costs. You can, however, pay additional costs, such as kicker costs. If the card has any mandatory additional costs, such as that of Tormenting Voice, those must be paid to cast the card.

If there are no instant or sorcery cards in your graveyard as Living Lore enters the battlefield, it will enter the battlefield as a 0/0 creature and be put into its owner's graveyard due to having 0 toughness.

If a spell has {X} in its mana cost, you must choose 0 as the value of X when casting it without paying its mana cost.

If Living Lore leaves the battlefield, the ability that defines its power and toughness will lose track of the exiled card. Its power and toughness are 0 in other zones.

Living Lore's last ability will trigger whenever it deals combat damage, no matter if that damage is dealt to an opponent, an opposing planeswalker, or a creature it's blocking or being blocked by. You choose whether to sacrifice Living Lore as that ability resolves. If Living Lore has already left the battlefield, perhaps because it was dealt lethal damage at the same time it dealt damage, you can't sacrifice it.
