You can kinda cheese past it if you have most of the healers die, get the raise buff roughly around when Amon casts curtain call, wait for it to just go off and then dead heals take the rez, and begin raising sacked healers plus tanks.

It took effort to do that though, and that doesn't include the juggling of constant frog debuff, adds, bombs, -aga spams, and Amon clearly on your healer butt in aggro if tanks die again. :')
