"✪ Earthbound Prisoner Stone Sweeper" Rating Score by 波切

A card that attracts attention as it allows you to search for Jack Strak's new 《Soul Resonator》.
The search effect (2), which is likely to be used in the main, has a disadvantage that "until the end of the turn, you can only Special Summon Fusion/S monsters from the EX Deck", but his Deck does not depend on Xyz or Link. If so, there should be no problem.
Not limited to 《Earthbound》or 《Resonator》, it has a powerful search effect that “adds 1 Fiend tuner of level 3 or lower from the Deck to your hand”, so it seems to be useful as a general-purpose card. It seems to be a card that can also be used in 《Fabled》and 《Infernity》(Are Malebranche of the Burning Abyss and DD difficult?).
Another way I can think of is to use this card to search for "Amanokujaki" in the "Lair of Darkness" Deck, transfer control to the opponent, and declare his DARK to harass him. It's weak as a lock, and you'll need to devise ways to prevent your opponent from removing it. If you simply want to send a monster to your opponent's field, it may be practical.
Also, although this card is level 5, if you have a Field Spell, you can Special Summon yourself with the effect of (1), so you can use yourself as a material if necessary. This does not trigger his Special Summon binding, so it can be used as a Link or Xyz material. It may also be possible to use it in a 《Archfiend》Deck that uses 《Pandemonium》.
