Blightbeetle

Creatures your opponents control won’t receive +1/+1 counters as they enter the battlefield.

Blightbeetle doesn’t remove any +1/+1 counters already on creatures your opponents control.

If the cost of an ability or an additional cost of a spell requires putting +1/+1 counters on a creature affected by Blightbeetle, that cost can’t be paid. If a resolving spell or ability says that a player may put +1/+1 counters on that creature, that player can’t choose to do so.
