If, during your declare attackers step, Ursine Monstrosity is tapped, is affected by a spell or ability that says it can't attack, or hasn't been under your control continuously since your turn began (and doesn't have haste), then it doesn't attack
The creature with this ability wasn't afraid
A deck designed around Henry Wu wants to ensure you have plenty of cards that trigger off of your creatures dying, while also proving plenty of ways to generate non-Human creature tokens to keep the value pile going
A card featuring their favorite deck's commander, their first booster pack, or a photo from their first GP personalized and printed on premium card stock is the kind of gift that gets framed, not forgotten in a drawer
You could hide him behind Bodyguard characters or just leave him unexerted
We love this bundle of commander decks, because of how they are designed to be played against one another
