Where does this game / community stand on the use of proxies?

I love that they give you 'play-sets' when you buy packs, however, if you make multiple decks, and don't feel like buying another pack just for an objective set, can you proxy it / them assuming you already own the sets?

For example, I have a single Executor objective in 2 different decks using the 2 copies i have (1 in each)...can i proxy it to use in a 3rd deck??

I don't mind proxies for casual play and/or play testing. However for tournament play real cards are required.

that's what I figured...this would be for casual when in the event i do actually play with some friends.

I have no qualms about ruining some MTG cards for this.

Well why not using the same cards for your 3rd deck instead of proxies?

The pod-like building makes it easy to move cards around different decks ...

Use the same colored sleeves for those decks, make a note in blank sleeves as to which cards belong in those places, and switch them out between games. That's how I like to do it anyhoo.
