My only criticism is the fact that you choose a card at random for her triggered ability, yet take the bottom card for her activated. How do you choose a card at random without shuffling the yard so that you don't manipulate the order? Sounds like a judge nightmare lol
I really want to leave it at pain mana for this. If i up the neutral mana by 1, would that work? so it's 2 mana and 6 life instead of 1 and 6 life? Leaving the bestow at 3mana + 6life? Or, could I make it normal mana for normal casting, but pain mana for bestow? So, 4 total for normal, and 3+pain as written for bestow?
