by @UppedHealer8521 Stylish Sleeves Challenge - Adds the Stylish Sleeves Challenge to the game: The effects of all base game decks apply, X2 base blind score
Offers powerful decks built mainly from booster cards, suitable for both casual and competitive play, helping players reach the game's top levels easily
The front is crystal clear so you can admire every detail of your favorite cards, while Mega Charizard X blazes across the back.Whether its for tournaments, trade nights, or that secret treasure box under your bed the 65 Deck Protector sleeves in standard size are perfect for most trading and collectible cards (like the Pokmon TCG)
In the latter case, since the door becoming unlocked is what causes the ability to trigger, effects that cause abilities that trigger when a permanent enters to trigger an additional time (such as that of Panharmonicon) won't apply
That would make you gain 14 upgrade exp with a 13 exp penalty for adding new cards (which would still be net-positive)
