MTG Salvation

I ordered two beseach the queens for my zombie deck mostly because I already have 4 final partings which allow me to throw my grave crawlers into the graveyard and tutor for a card like rooftop storm or sidisi undead vizier, to put into my hand. At that point beseech the queen allows me to go for a 2-3 drop like eternal taskmaster, death baron or lord of the undead faster than a diabolic tutor. Alot of good zombies have low casting cost so I could see beseach the queen as a faster way to get important zombies on the field if you hadn't already hit them by turn 3. I'm replacing my 2 diabolic tutors with beseach the queen, so we'll see how my theory holds up.
