It's annoying enough when people use those half-baked point systems
to compare cards, but it gets even sillier when people bring
commonality into the picture.  You can't say a card is better because
it's easier or harder to get...whether a card is shiny or not means
nothing in the middle of a game!  If you think one card is better
than another except for rarity, are you honestly going to say, "This
one is cheaper; therefore, I'm using it instead"?  If you do, you are
the type of person that makes me wish I could play in a tournament,
just so I could try out my rarity-indifferent decks.  I make them all
without ever looking at the little circles and stars because they
have nothing to do with gameplay.  Try it and maybe your decks will
turn out better because of it.
