Mega Magcargo's Defense?

So I was checking Mega Magcargo’s base stats to ensure they hadn’t changed, and they have most definitely changed. It’s base defense was 10. Is it suppose to be 10? It’s base stat total was 430, which is only 20 more than Magcargo, so I figured that this might be an error. Mine is 31 IV except Attack which is 8, with 252 EV in Sp. Def and HP and 6 in Sp. Atk

Its defence is,I think base.But yours is lvl 70.And deltas have same or a bit high or low,but not that different stats.So it may vary with the normal one a bit.

But this is a Mega, not a Delta. Delta’s have the same base stats, but Mega’s usually gain 100.
