Its presence here seems to be due entirely to the Pokmons popularity, in a set with little else to attract collectors whore only familiar with the first couple generations
It means you can squeeze that game in while on a tea break, at the bus stop, or during a definitely very important and relevant compulsory remote meeting about nothing to do with your department, without worrying about damaging your ranking or score if you have to duck out early or just make a silly mistake
When your opponent activates a card or effect (Quick Effect): You can remove 1 Borrel Counter from this card
Its worth noting that Boros Charm protects more than just creatures
There are no Fish, Reptile, or Thunder "Number" monsters
