Ungraded & graded values for all One Piece Japanese OP10 One Piece Cards
W for a 1/1 (So far, so good.) 2W for a 2/2 (Pearled Unicorn, but not horrible.) 10W for a 5/5 first strike creature (Wait, what?) 1U for a 0/3 (Eh, but bearable.) 3U for a 0/6 (Getting pretty bad here.) 11U for a 6/6 islandwalk creature (Wait, what?) B for a 1/1 (Muck Rats, but okay.) 4B for a 3/3 (Looking a little worse here.) 12B for a 5/5 creature with pseudo-fear (Wait, what?) Those ultimate mana costs were paid out over multiple turns, but if your creature died before hitting their highest level game over, tons of wasted mana, yikes
You can only use this effect of "Archfiend Heiress" once per turn
It has good stats for its cost, provides minor, repeatable graveayrd hate, and even gives you cost reduction with the right set-up
