Ursula - Deceiver of All

Clarifications

When can I play the additional song using Ursula - Deceiver of All's ability What a Deal?

When using the What a Deal ability of Ursula - Deceiver of All, you must play the song immediately after you played it the first time. You can't wait until later in the turn.

The only character in play is my Ursula - Deceiver of All, who currently has 1 damage. If I have Ursula sing Let the Storm Rage On, can I use her What a Deal ability to play it again?

Yes. When you play Let the Storm Rage On, if there's a character in play you can choose to deal 2 damage to, you must do so. Even if Let the Storm Rage on banishes your Ursula - Deceiver of All, you can still use her What a Deal ability. In this case you won't be able to deal 2 damage to a character, as there aren't any in play, but you still draw a card.

My Ursula - Deceiver of All sings The Boss is On a Roll. I choose to place 4 cards on top of my deck and 1 card on the bottom. If I use her What a Deal ability to play The Boss is On a Roll again and choose to put 1 more card on the bottom of my deck, where does my copy of The Boss is On a Roll go in relation to the other cards I placed on the bottom of my deck?

The Boss is On a Roll will be the bottom-most card of your deck, regardless of how many cards you put on the bottom of your deck each time you played it. The card played a second time with Ursula - Deceiver of All's ability What a Deal is placed on the bottom of your deck after its effect has finished.
