See http://www.magicmultiverse.net/cards/92300 in "25th Anniversary Cube".

Dominaria spoilers suggests this will be the preferred way in the future to implement these kind of variable p/t creatures.

I dislike this wording change simply because it removes the * symbol from cards which looks really cool in the p/t stat box.

I understand why they're making the changes from a rules perspective but from an emotional perspective I'm sad to see it go and will use the old style in my cards when possible.

(I won't be naming my one Legion since the cube supposed to be nostalgia orientated and not introduce new planes/factions. Feel free to use it here and congratulations on the art and flavour text.)

The change seems similar to what I've been doing with "you get X, where X is blaa" texts by essentially replacing them with "for each blaa, you get 1" or "you get X equal to the number of blaa".

Yeah, no card references here so that makes sense.

EDIT: I started looking for existing cards to pick out those reference points, but I find that references in general are kind of weird actually. It's not that much of a stretch to say that this refers Revenant, Scion of the Wild, and/or Crusader of Odric though not explicitly so. Flavor text on Revenant especially is quite similar and the general themes are close, even with Crusader.
