Counters and Un-cards Rulings

Hello Mark, I have an un-rules question. Saw the Giant Fan came up recently and I've been considering it for a Cumulative Upkeep themed deck. Do counters referenced by keywords but not explicitly mentioned in the text count for Giant Fan? If I were to move a Velocity counter from Tornado onto a Herald of Leshrac, would that counter be turned into an age counter because Cumulative Upkeep refers to age counts implicitly, or would it be turned into a +1/+1 counter because the reference to age counter is not in the actual text but only in the comprehensive rules? My understanding from un-sets is that "rules text" usually only refers to the non-italicized oracle text in the text box of a card, but I'm not sure that's correct.

When Unsanctioned came out, we did an Oracle pass on the Un-cards. Giant Fan now cares about cards that “refer to” rather than caring specifically about rules text, so reminder text would matter. We’ve also ruled that if the counter is inherent to the card type, it will also get the counter, so using a Giant Fan to move a counter onto a planeswalker will get you a loyalty counter.
