Players are rolling the die to get a free 7/7, but youre in trouble if you planeswalk and dont have big creatures
With some careful deck building (mostly playing some big card-draw spells you can cycle into with Unpredictable Cyclone to make sure you always have some cycling cards in hand), you should be able to mostly play your entire deck in a single turn by cycling, casting stuff (including card-draw spells) for free with Unpredictable Cyclone, drawing into more cycling cards, and cycling them to trigger Unpredictable Cyclone against and again until you've essentially cast your entire deck
Both discourage attackers from coming your way but instead use a resource that your opponents will always have in life and the creatures themselves
Custom decks can be great wedding favors, birthday gifts, and conference giveaway items
Signets and mana rocks like Boros Signet, Rakdos Signet, and Heraldic Banner ensure you can cast your vampires ahead of curve and keep the momentum going
