I remember jamming this card in my early days of playing Magic--it was easy to recognize the card's power even as a young player
In fact, what made these rare cards rare was specifically the fact that these ability were "off-color." Equivalent versions in the proper colors show up in the set at lower rarities
Almost every ally creature in Magic: The Gathering has an effect that buffs every other ally, gets better the more allies are on the battlefield, or triggers when more allies come into play
Note that you essentially cant play around this in isolation, as its far too rare to put them on unless they have one
There are a few stand out cards that I'm sure will see play, but beyond those 2-3 the set gets very deep, with a bunch that are good enough to see play, but not strong enough to outclass all the others
