This card is very similiar to the most expensive Lorcana card from The First Chapter
Every time this Enchanted card quests, a player can look at the top two cards of their deck and take one while returning any unclaimed cards to the bottom of the deck
(If this creature isn't monstrous, put X +1/+1 counters on it and it becomes monstrous.) If Maester Seymour is no longer on the battlefield when its first ability resolves, use its power as it last existed on the battlefield to determine how many +1/+1 counters to put on the target creature
Keep in mind, though, that decks you build for the competitive meta might not be as strong in this format, and vice-versa
