This is one of the most common misconceptions that we run into when playing against Obeka decks online and a recurring theme that we notice when checking decks and looking at which cards people include in their list
There are many ways to check for counterfeiting on the market (differences in printed color, examining the print with a magnifying glass, difference in weight, passing through strong light, bending test, 5
Roughshod Duo enables both aggressive raccoon and mice decks, for example, while Lightshell Duo fills the graveyard for rat decks and plays well with the spells otter decks depend on
But when it comes to interacting with the other mice, it honestly feels lacking, especially for a type that is iconically synergistic, with so many cards designed to interact with each other and dependent on teamwork
If an Adventure spell leaves the stack in any way other than resolving (most likely by being countered or by failing to resolve because its targets have all become illegal), that card won't be exiled and the spell's controller won't be able to cast it as a permanent later
Even something as simple as giving all of your Werewolf Creatures flash would work, because you need to be picky about when youre casting spells to decide if you want things to transform or not
