I agree with quanta denial vs. Aether. Dim shields are 6. Fractal is 9, Parallel Universe is 7, all their critters are overpriced (except Phase Spider, but it's in the opening damage range for Drain Life). Quint is cheap and strong though. So they can field delicate but dangerous critters and expect them to be protected. Lobotomizer also needs to be considered, although they'd have to protect it. Mind Flayers are also in opening damage range for Drain Life, but they could be quinted even with quanta control slowing them down. Three quanta is always easy.
Lightning is amazing CC. It kills every Darkness creature that hits the table instantly (barring Voodoo Doll). Gargoyle and Lycanthrope both need to survive unmolested for a turn until they can survive a hit.
