Ruling MooMoo Milk

[Cinema]

The old version of Moo-Moo Milk which is now spelled without a dash as MooMoo Milk. Can I still use the old one in tournaments?

The answer is no, as per the Compendium:

Q. Do I need to have a current version of "Moomoo Milk" outside my deck if I'm playing the older versions of the card in Modified Format?
A. Technically speaking the "Heart Gold/Soul Silver" version is a different card and it does not do the same thing as the older versions used to (it removes more damage counters now). So you cannot play "Moo-Moo Milk" from "Neo Genesis" nor "Expedition" in the current 2009-2010 Modified Format. (Feb 18, 2010 PUI Rules Team)
