I had no idea that you could force a draw in MTG. Did they have to add a rule specifically for infinite loops? Are there other infinite loops?
Also, this sounds like a troll deck.
You can also cause a draw by using a damage effect that kills both players at the same time (as with Hellfire in Hearthstone if you play that).
They did have to add a rule specifically to clarify infinite loops. Basically these situations are "everybody starves" situations, which for Donald is fine but for a Magic tournament where a match slip needs to be turned in and say "win, lose, or draw" on it, they need to clarify (well, actually I guess the time-out rules would cover it eventually but that's not desirable).
The most famous other infinite draw loop I can think of Animate Dead:

http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=383154. There used to be a Legacy combo deck based on those two cards. If you play Animate Dead targeting a Worldgorger Dragon in your graveyard, you resurrect the Worldgorger Dragon, which banishes the animate dead, which kills the Worldgorger Dragon, which unbanishes Animate dead, which resurrects the Worldgorger Dragon, and then it loops. Like 90% of the time you could kill your opponent using the other permanents that keep jumping in and out of existence, because they untap and refresh each time they come back so if they can do any thing to kill your opponent, they will have infinite opportunities to do so. (even a modest card like
http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=270806, I don't know which card the deck actually used.)
However, if you don't have a way to use the loop to kill your opponent, and there are no other creatures that Animate Dead can resurrect after you resurrect the Dragon a few times, the loop goes infinite and draws the game whether the Worldgorger Dragon user likes it or not.
Worldgorger dragon has since been banned from Legacy even though the rather powerful Animate Dead is still allowed. The ability to easily get kills plus the backup plan of drawing the game if you're in a tough spot is pretty strong.
Neither card is restricted in Vintage so you can still do that combo there. It might actually be decent, I don't know if it sees play.
