Lord Skitter's Blessing

Some spells and abilities that create Role tokens require targets. If each target chosen is an illegal target as that spell or ability tries to resolve, it won't resolve. The Role token won't be created.

Cards in the Wilds of Eldraine main set create six different Role tokens: Cursed, Monster, Royal, Sorcerer, Wicked, and Young Hero. A seventh Role token, Virtuous, is created by Ellivere of the Wild Court, the commander of the "Virtue and Valor" Commander Deck.

Hexproof and shroud won't prevent a Role from becoming attached to a permanent if the ability creating that Role attached to that permanent doesn't target it.
