first edition entei pokemon card Entei-Holo (6) 2001 Neo Revelation Aquapolis Type Pokemon - Entei (34) -

(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

Collector Boosters may contain these cards: EOE 1266, 277392

Honorable Mentions Before we commence, let's start with an appetizer

For instance, "Witch's Oven" creates food tokens

Virtue of Loyalty I think the entire Virtue cycle from Wilds of Eldraine is at least playable

Maybe if the blue decks really end up being about tempo and pushing damage I will change my mind
