Shiny Museum 2 Shiny Museum 2 tasks you with finding five cards, but don't be fooled, they are all Shiny Mega EX Cards which can take a significant amount of time and luck to pull
This is a Grixis creature that gives you additional upkeep steps, which isnt necessarily doubling abilities
Despite how long the creature type has been around, there is actually a rather small number of Rat cards, with only about 100 Rats in all of Magic
Some points of comparison were that its a bad Impulse because it doesnt dig very far in the early stage of the game, evaluation tends to be focused on how cards play when on-curve, ignoring how it scales later in the game because its not a common axis of evaluation, but I found that it played remarkably well on turns 5+ (like this, in Historic) and was still fine when cast on 2 mana
At just over $40, its a fan-favorite pull for Galar region enthusiasts
