Robby, Another Dwarf is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

Official card text

Dwarf creature spells, legendary creature spells, and Equipment spells you cast have squad 2. Tokens created this way aren't legendary. (As an additional cost to cast one of those spells, you may pay any number of times. When that permanent enters, create that many tokens that are copies of it.)
