Idol of False Gods

If Idol of False Gods loses its abilities, the type-changing effect of its last ability will continue to apply to it. This is because effects that change an object's types are always applied before effects that remove abilities. In that case, if it has eight or more +1/+1 counters on it, it will be an Eldrazi kindred artifact creature. This is true even if it somehow gained its eighth +1/+1 counter after losing its abilities. If Idol of False Gods loses its abilities before gaining its eighth +1/+1 counter, it will have annihilator 2; otherwise, it won't.

Annihilator abilities trigger and resolve during the declare attackers step. The defending player sacrifices the required number of permanents of their choice before they declare blockers. Any creatures sacrificed this way won't be able to block.

Kindred is a card type that allows noncreature cards to have creature types. For example, Echoes of Eternity is an Eldrazi (although not a creature) while on the battlefield and an Eldrazi card (although not a creature card) in zones other than the battlefield.
