The other use I can think of is that Karn's card draw isn't worded as "drawing," so if you're a horrible person and want to lose your friends, you can pair Karn with mean cards like Possessed Portal or Omen Machine to lock them out of the game while you keep your hand nice and full
Yes, rarities often determine how useful or strong a card is, but this is only one factor
There's simply something about this card that makes it really "pop," whether that be the elegantly designed attacks or the original Sugimori artwork, but collectors seem to agree as it retains a high price point today
These missions reset every 24 hours and typically include logging in, opening booster packs, making one Wonder Pick, and participating in a battle
However, please note that resubmitted corrected artwork counts toward the maximum submission limit of three pieces of artwork
These offer both design and flavor benefits in the game, simplifying how you understand the cards while also tying the abilities to the set and the story in a way that wouldnt be possible without them
