How many times is Edge going to challenge The Deadman for the WHC?

first of all, he failed to end The Undertaker's undefeated WrestleMania streak (which will never end), then he failed to win back the title at Backlash. And then The Phenom was stripped of the title. And just recently, they both battled for the vacant title at Judgement Day, which Taker won via countout. But of course, neither men won the title. When will this fued end?
