Good idea, Destroyers do the more damage for less quanta (9 damage after growth). I put in minor phoenixes which can be played a turn faster off the mark. They can also net you more death quanta and allow you to do more damage.
New Strat: if you have a minor phoenix on the field and a spark/cremation in your hand, you can play the spark to get you death quanta and do five damage, then immolate the phoneix. this gives you +1 damage for the turn and all that quanta.
New on wishlist: pumpspell for death
