Did you remember this mechanic
This means that all permanents retain their other types in addition to being artifact creatures.) This combination not only causes all kinds of shenanigans, the least of which is most certainly not the fact that all lands die because of being creatures with 0/0 power/toughness (unless there's something else increasing their toughness), but it also allows many interesting interactions with non-creature permanents that are not normally possible (because most of the "interesting" interactions usually target creatures and nothing else.) Just to mention one of the numerous possibilities, take for example the situation where Clone enters the battlefield as a copy of Garruk Relentless
Any enters-the-battlefield abilities of the copied enchantment will trigger when Estrid's Invocation enters the battlefield
It only takes one or two activations to overwhelm your opponents
