Aatchik, Emerald Radian

When Aatchik enters, create a 1/1 green Insect creature token for each artifact and/or creature card in your graveyard.
Whenever another Insect you control dies, put a +1/+1 counter on Aatchik. Each opponent loses 1 life.

Aetherdrift

If Aatchik is dealt lethal damage at the same time as another Insect you control, Aatchik’s last ability will still trigger, causing each opponent to lose 1 life, but Aatchik won’t get a +1/+1 counter in time to save it.

If a card in your graveyard is an artifact creature card, count it only once when determining how many Insect tokens to create for Aatchik’s first ability.
