Your definition of combo makes every deck combo. "The whole is greater than the sum of it's parts." To exemplify - Landstill. Faerie Conclave is not the best card ever. In fact, in most situations, its pretty bad. However, teamed up with a deck that uses it to apply pressure under Standstill, clears the way for it with removal, and stops opposing removal with counters, the card is a lot better. Is this a combo deck? I wouldn't even suggest it as one. How about a deck that utilizes cheap draw spells and untap effects to basically cycle through its whole deck, winning with the resolution of a single spell which rewards the caster for spells cast before it this turn. Is that a combo? Only if you consider the combination cards:
1) High Tide
2) reset
3) Meditate
4) Cunning Wish
5) Words of Wisdom (or another card to make your opponent draw)
6) Brain Freeze
7-X) The whole rest of the deck to up the spell count enough to make it work.
This is why I think it's a misnomer to call Storm decks Combo.
As for Vial Goblins, the interaction between the parts is combo-esque, with the acute possibility of a turn 3 win (it happenned to me twice at Big Arse, once with 3 Piledrivers, once with Pyromancer). While I would agree it is an aggro deck, I grouped it with the Combos for this reason. That said, I think the same logic I'm applying to Storm can be applied to Gobbos.
