However, I'm still not convinced that Fallout is always better. Importantly, Apes, Nacatyls, pairs of Elf Lords, etc. are all Shock-proof. If I turn 2 Keldon I'll simply swing then sweep to avoid killing my dude early. In my experience most people will not want to trade their "good" creature with a "throwaway" creature, which is something that I'll happily capitalize on.
