Sorry if things seem random, but yes, you should be able to find their definitions as you go through later parts of the thread. Twilight Ram is supposed to be a severely devastating Dark-type version of Double-Edge, in which the user can takes almost half the damage caused as a recoil; however, if the attack misses, the user faints from exhaustion anyways. Genome Shift actually forces the target to transform into a Pokemon that's weak against one of the user's attack moves (but I don't remember if that was the only effect...).
