In this situation, you would end up with only 7 lands.
The former Blinkmoth Nexus will be named Augmenter Pugilist, be green, be 1/1, have trample, flying and the +5/+5 ability, and have the types Artifact Creature -- Blinkmoth.
Notably it will not have the Land type.
It is important to understand that the phrase "It's still a land." does not add the Land type to the affected object. That phrase has the same meaning as "in addition to its other types."
In this instance, a separate part of the rule strips the previous creature subtypes so only Blinkmoth remains.
A clarification here. Because Blinkmoth Nexus's second ability makes Blinkmoth Nexus a "Blinkmoth artifact creature", it will lose all creature types other than Blinkmoth but still retain all card types, subtypes, and supertypes other than creature types (C.R. 205.1b).
This is due to the last sentence of C.R. 205.1b, which deals with the text "[creature type or types] artifact creature" and was added with the rules update for Throne of Eldraine. According to the update bulletin for that set, the sentence is intended to modify the "artifact creature" exception to the general rule that if "an object is said to become a certain list of types, these overwrite any other types it has" (review C.R. 205.1a).
However, Blinkmoth Nexus's second ability also has the text "It's still a land", and I admit that applying that part of C.R. 205.1b can be tricky for Blinkmoth Nexus and a handful of other cards that not only have text of the form "[creature type or types] artifact creature", but also have the text "still a [type]" (e.g., Inkmoth Nexus, Dread Statuary, Frostwalk Bastion, Mishra's Factory, Stalking Stones).
- Will I still have 8 lands on the battlefield?
- What types would the Blinkmoth Nexus have?
- Assuming I still have 8 lands on the battlefield, would the Blinkmoth Nexus now be a 6/6 creature with flying and trample?
Thanks.
