If I trigger Overzealous Fan, can I still play an action?
Yes, you can still play an action after triggering Overzealous Fan's ability.
According to RiftJudge FAQ #8798 and FAQ #9694, a combat showdown does not end immediately when a unit is moved or removed from the battlefield (such as by Overzealous Fan). The showdown continues until both players pass consecutively with focus on an empty chain. Even if Overzealous Fan is killed, the showdown remains active, and you retain the opportunity to play other [ACTION] or [REACTION] cards provided you have the focus to do so.
Understanding the Timing (Unleashed Update)
The rules regarding the "kill me" cost for Overzealous Fan were updated in the Unleashed patch. Based on RiftJudge FAQ #8702 and FAQ #9611, the interaction functions as follows:
- Trigger Condition Met: When Overzealous Fan gains the "Defender" designation during a combat showdown, its ability triggers.
- Optional Choice: Because the ability text says "you may," the ability is optional (Rule 383.3.a).
- Paying the Cost: If you choose to use the ability, you must kill Overzealous Fan upfront as a cost to place the ability on the chain (Rule 383.3.b.1).
Summary: Because the showdown persists after the Fan's ability triggers, resolves, or is countered, you are free to continue playing actions until the showdown officially concludes by both players passing priority on an empty chain.
Note: I could not fully verify the specific mechanical state definitions referenced in the draft against the retrieved rules.
