What strategies and cards should I consider when building a competitive Worldslayer deck for tournament play?

When building a competitive Worldslayer deck for tournament play, consider including cards that can protect Worldslayer, such as counterspells or indestructible creatures. Additionally, include cards that can help you quickly equip Worldslayer to a creature, such as Stoneforge Mystic. Other strong cards to consider are those that can generate mana quickly, like Sol Ring or Mana Crypt, to help you cast Worldslayer early in the game.
