Take a look here:http://infinity-wars.wikia.com/wiki/Understanding_Infinity_Wars_Cards
1-) When I mentioned "inside the blue box", my intention was to say that the "Card Name", "Keyword Abilities", "Type/Supertype/Sub-type" do not appear. So, what the player would see using Pure Art was only
the art of the card.
2-) Player can still see what is "outside the blue box", so, Rarity, Attack/Health, Faction Purity, Resource Cost, Morale Cost, Artist and Set/Card Number still appears.
3-) The card text says that "Player can choose to play the game seeing only the art of his
cards [...]" so, it does not punishes new players.
What is the intention of this card? Experienced players who already know what a card does now have the option
to play the game seeing only the art of the cards of his deck, so, players like me that loves the art of the game can see the cards art as a whole, without anything in front of it.
It is a way to promote a different game play mode.
At the first turn, if u have the card at your deck, as it has "opening", the card plays itself and the game asks you: "Do u want to play the game seeing only your cards art? Yes / No."
After, the card disapears.
If you still think this is not appropriate for the challange, I can make something different.
