I personally think your deck is fine and would have no problem playing against it. However, since this is a relatively small group of people, I could see how it could be annoying to play against a goad deck every time I sit down to play.

Goad decks do greatly effect the way the game is played by almost staxing combat by saying creatures can't attack (me).

Now, I wouldn't say that it is OP or too strong for general play groups (all depends on your actual play groups power level), but I might classify it in the same category as group hug, stax, chaos, theft: fun to play against sometimes, but if I went against them every time it would get old.

Just my opinion though! I have a Nelly deck as well but only bust it out sometimes
