Immunity to status
Immunity to damaging weather
Not to mention Life Orb Alakazam is stronger than MegaZam, without the penalty of LO recoil. He can also run Sash sets without worrying about it getting ruined by any of the shit I listed above.
Zam's problem wasn't his speed. It was his incredible frailty and somewhat lackluster offensive movepool in a metagame where other sweepers with more bulk and better coverage and utility exist. Magic Guard was the only thing keeping him relevant.
MegaZam doesn't fix either of those problems and takes away that incredibly important ability AND uses up your Mega slot. He's trash.
