Link Joker focuses on limiting the opponent's ability to fight back. It does this via the Delete mechanic, which weakens the opponent's vanguard and removes their abilities, to make your attacks harder to defend. Aside from deleting the vanguard, the clan also binds the opponent's cards face-down, while the Starhulks can manipulate your ability to trigger check, or reverse trigger effects themselves and Messiah and its followers put units face down in the field (lock) in its field to activate various effects or to make unlock taking more attacks, in the case of the Star-vaders can use the manipulation of the face down cards in the field (lock) in an offensive mode to placing face down cards in the opponent's field it can also demolish your opponent's Imaginary Gift to ruin any advantage.
Link Joker uses the ForceImaginary Gift to capitalize on the opponent's vanguard being deleted, or their triggers being reversed with your increased power, or get more criticals to compensate the locked field. This also grants you more Force markers every time you demolish an opponent's Imaginary Gift.
