Bionicle at the surface may seem very different than Magic The Gathering(Commonly known as Mtg) however both are very similar in many aspects. Hopefully this post will convince you that Mtg is a near perfect substitute for Bionicle.
-Both have a deep lore.
-Both have a physical medium(toys/cards) that you can collect and relate to certain characters and story revalent scenes.
-Both have a creativity aspect. In Bionicle it’s mocs and in Mtg its decks that you build.
-Both have different elements that represent elements and correspond to characters.
-Both have a very devoted fan base that creates theories and artwork for the fandom.
If Mtg interests you in any way I suggest that you download Magic Duels, it’s free and it’s a great way to learn the game.
