one piece trading card game illustration box Amazon.com: TCG Vol. 3 1 × Special DON Bandai Namco One Piece Card

You can call it canon at any time because thats what the multiverse implies, but at the same time those promotional cards were just card styles and not actual standalone cards like the Street Fighter or Walking Dead Secret Lairs

If you prefer to play in formats such as Standard or Alchemy, it is not recommended to spend wildcards on spells that will soon be taken out of rotation

If Deadpool took the Textbox of Alexios, even though Deadpool's name would not change, it would gain all of the abilities that affect Alexios

It also works if you can reduce its untap ability to 2 or less

The sky is the limit with Xenagos, The Reveler, and the amount of all-around value that comes from the card makes it easily the best Gruul planeswalker out there.
