You can obviously still play Magic's best Mardu card in Duel commander with friends if they agree to it, but keep in mind that it might be a controversial deck
Souls creates up to four flying Spirit creature tokens for a relatively low mana cost
I've seen that some players are using them in casual Derevi decks, and this seems like the perfect home for Keeper of the Nine Gales, thanks to its untap effect
Upon further reading and seeing no ultimate, those fears were alleviated
For example, Complains Clerk has "Whenever you roll a 1, create a 1/1 white Clown Robot artifact creature token." If you choose that ability, you ignore everything up to the first comma, ending up with "Create a 1/1 white Clown Robot artifact creature token." Some triggered abilities have an "intervening if" clausethat is, they are written in the form of "When/Whenever/At [trigger event], if [condition], [effect]." If you choose such an ability with Trigger Happy, you ignore the trigger event, and the ability will go on the stack even if the intervening if condition is not fulfilled, but the ability will still check the intervening if condition as the ability tries to resolve
