There is a 1 in 3 chance for a Marks in Time booster pack to contain a Super Rare, Ultra Rare, or Royal Rare card in place of a Common card.

In addition to the main set, there are also 2 Royal Rare (RR) parallel alternate-art full-card cards. These Royal Rare (RR) versions are full-card (borderless) versions of 2 Ultra Rare cards found in the main set but are otherwise the same as their main set equivalent. There is a 1 in 216 chance for a Marks in Time booster pack to contain a Royal Rare (RR) in place of a Common card (average of 1 per case of 6 booster boxes of 36 booster packs).

The promo set of 11 cards cannot be found in booster packs. All of these Promo (P) cards are alternate-art foiled versions of cards in the main set (none are unique to the promo set).

There are no theme decks released for the Marks in Time set. Instead, there are 3 versions of the Make Your Mark Pack Drafter, meant for use in Limited Draft events.
