"TIL that Poison/Ground is the only type combination that hasn't been revisited since Gen 1"

Assuming Mega Evolutions and later (pre-)evolutions count as the gen in which they were introduced, the Nidoran line's Poison/Ground is the only unique type combination for 7 straight generations. Clearly this is an indication that we needed Mega Nidoking and Nidoqueen.The list expands to include the Gastly line's Ghost/Poison, Zubat line's Poison/Flying, and Jynx line's Ice/Psychic if evolutionary families are grouped by the generation they were first introduced.For reference: http://ift.tt/2jgUICn via /r/pokemon http://ift.tt/2ihw1S9
