Question about multiple accounts

When this game comes out, I wont lie, I'll probably drop fifty bucks or so in packs to start building decks. Later, however, I think it would be fun to start a new account (since it's an f2p game and all) without spending a dime on it to see how long/ how difficult it would be to get a high rank that way.

My question is if Phenteo or anyone else can tell me if there is any reason I won't be able to have more than one account?
