"Earthbound Immortals" are very strong, but cards like "[[Ancient Fairy Dragon]]", "[[Black Rose Dragon]]" and "[[Mystical Space Typhoon]]" could destroy an active Field Spell necessary to keep one around and take the Earthbound Immortal with it. You can use cards like "[[Field Barrier]]" to protect your Field Spell from being destroyed. Be careful though, cards like "[[Murmur of the Forest]]," "[[Giant Trunade]]," and "[[Codarus]]" can simply remove the Field Spell without destroying it, effectively not only bypassing "Field Barrier," but also disallowing you to play another Field Spell until "Field Barrier" itself is removed somehow. "[[The Seal of Orichalcos]]" also works well in this deck, as one of it's effects helps prevent destruction, as well as boosts your monsters by 500 ATK.If you don't want to have this worry at all, you can use either "[[Hardened Armed Dragon]]" as a Tribute so that your "Earthbound Immortal" cannot be destroyed by card effects (including its own) or Summon an "[[Earthbound Linewalker]]" for the same protection. In an emergency situation, "[[Skill Drain]]" might also help to protect them. Also the Majestic Dragons are a major threat to the Earthbound Immortals because they can negate the Immortals and (depending on the Dragon) can negate their effects and use them/gain their attack points giving the two a superb advantige.
