Hmm... I run a deck with 4 emerald towers, 3 life pendulums, 2 feral bond, 4 mitosis (13 Life)... 6 obsidian towers, 5 pests, 4 obsidian dragons, 1 eclipse, 2 siphon lifes, 3 improved steals, 1 vamp dagger (22 Darkness)
35 card deck that has relatively balanced quanta, and can quickly overwhelm a deck. If the opponent has a bad draw, this deck will annihilate them.
