Doing Partner's Moves
You can do your partner's moves when you have your "Special" in Tag Team Matches. They are all done the same way. Hit the A Button, B Button, L Trigger, and R Trigger at the same time when you have a "Special" to perform the move.
For grapple moves this must be done while you have your opponent in a Strong Grapple. Here are the different moves you can steal with some examples:
Front Special:
You'll always do your partner's Special here.
Ex: Kane can give his opponent the Last Ride if Undertaker is his
partner.
Back Special:
You'll always do your partner's Back Special here.
Ex: Edge can give his opponent the Impaler is Christian is his partner.
Turnbuckle Grapple:
You'll always do your partner's Turnbuckle Grapple Special here.
Ex: Road Dogg can give his opponent the Bronco Buster if X-Pac is his partner.
