Anton is playing vs Nate in a GPT. During the declare attackers step Anton declares Anafenza, the foremost and Rakshasa Deathdealer as attackers and immediately places a +1/+1 counter on the deathdealer. Nate asks Anton to hold on as he wants to respond to the trigger from Anafenza with bile blight. Anton responds to that with activating the +2/+2 ability. Players move on to the declare blockers step and from that to the damage step. Anton notices he forgot re-resolve the Anafenza trigger and calls a judge.

How would you rule? He remembered the trigger but then forgot it. Do you rewind or leave as is?

This seems to be be textbook one of the case the modification of the missed triggers policy apply.

I don't believe the trigger can be considered missed. He declared the target, he just forgot to put the counter/to resolve an ability that was on the stack. Looks like a Grv to me.

That's exactly what the new change is about though. In order for you to have not missed the trigger, you have to do the accompanying physical action (mark life total change, put counters on, place token on field, etc) otherwise the trigger is missed.

Renato is correct here. The player correctly indicated awareness of the trigger which they must do by choosing a target. They have fulfilled their obligation there per the missed trigger policy and any further issue is handled as GRV.

New MT PIG requires ta physical action to complete trigger in this case so it's GRV.

Let's start and take a look at the IPG:

A triggered ability that requires its controller to choose targets (other than ‘target opponent’), modes, or other choices made when the ability is put onto the stack: The controller must announce those choices before they next pass priority.

Well, Anafenza requires a target and Anton chose one at the appropriate time, so no MT but GRV.

A triggered ability that causes a change in the visible game state (including life totals) or requires a choice upon resolution: The controller must take the appropriate physical action or make it clear what the action taken or choice made is before taking any game actions (such as casting a sorcery spell or explicitly
moving to the next step or phase) that can be taken only after the triggered ability should have resolved. Note that casting an instant spell or activating an ability doesn’t mean a triggered ability has been forgotten, as it could still be on the stack.

This does NOT apply here. The first thing that happens when Anafenza's ability triggers is choosing a target, so that's why it has to be declared immediately, even before the visible game state changes.
