I don't think it's a combo, but I wouldn't call it a nombo either - people use 'nombo' either to refer to things you'd think would synergize but don't (and I wouldn't think these would synergize) or things that anti-synergize (and I think these are basically just two cards).
You have to keep in mind that your slow-trashing, +buy cards are really really good for you here, and more importantly that you are speeding your opponent up quite a bit by your governors, so that's not so fast.
