Glint Hawk Idol

The creature type "Bird" was inadvertently omitted from each of Glint Hawk Idol's abilities. It has received errata to correct this omission; when either of its abilities resolves, it will become a Bird artifact creature.

If Glint Hawk Idol becomes a creature before you begin a turn with it under your control, it will be affected by "summoning sickness."

Wotc — January 01, 2011

If Glint Hawk Idol and another artifact enter under your control at the same time, Glint Hawk Idol's first ability will trigger. You may have it become a creature, but since it will be affected by "summoning sickness," it won't be able to attack that turn.

If either of Glint Hawk Idol's two abilities resolve while it's a creature, that ability will override any effects that set its power and/or toughness to another number, but effects that modify power and/or toughness without directly setting them will still apply.

For example, say one of Glint Hawk Idol's abilities has resolved and it's a 2/2 creature. You cast Giant Growth targeting it. It's now 5/5. Then Diminish ("Target creature becomes 1/1 until end of turn") is cast targeting it. Once Diminish resolves, Glint Hawk Idol would be 4/4. Activating Glint Hawk Idol's last ability at this point would make it 5/5 again until end of turn.
