More often than not every wrestler has that one 'specialty' match, whenever that type of match happens it's like home field advantage for them. Yeah they might lose but they have a high chance of winning because of their history.
Abyss? Monster's Ball
Cactus Jack/Mankind? Hardcore, HIAC or any kind of match involving weapons
Undertaker? Casket Match and HIAC
The Dudley's? Tables Match
That's what they're known for, it's THEIR match type because of previous battles they've had. It's where they're most comfortable and where they are most likely to succeed. There are exceptions to this though.
Would Ravens Rules count or Johnny Kidds Traditional british rules
