12/1/2004: Blinkmoth Nexus gains the creature type "Blinkmoth" when it becomes a creature. This means that it ends up with three types (land, artifact, and creature), plus one creature subtype (Blinkmoth).
12/1/2004: The "target Blinkmoth gets +1/+1" ability can target any creature with the creature type Blinkmoth.
12/1/2004: If Blinkmoth Nexus is turned into a Forest after it's turned into a creature, it ends up with three types (artifact, land, and creature), plus one creature subtype (Blinkmoth) and one land subtype (Forest).
2/1/2006: Because of the layering rules, if you have an animatable land, you can play the ability once, and then if it's power and toughness are lowered (but not lethally) by Mutilate or a similar effect, you can reactivate the land to restore them to those numbers.
8/1/2008: A noncreature permanent that turns into a creature is subject to the "summoning sickness" rule: It can only attack, and its {T} abilities can only be played, if its controller has continuously controlled that permanent since the beginning of his or her most recent turn.
