For Overzealous Fan's ability, do you choose the target unit before or after deciding whether to sacrifice the Fan? Does targeting count for Ezreal Legend's ability even if you don't sacrifice?

Ruling: You choose the target unit when the trigger goes on the chain, before deciding whether to sacrifice Overzealous Fan. The sacrifice decision happens on resolution of the trigger. Targeting an enemy unit counts as one of Ezreal Legend's two choices even if you choose not to pay the sacrifice cost.

Sequence:

• Overzealous Fan's trigger activates when it defends
• You choose a target enemy unit when putting the trigger on the chain
• The trigger resolves
• On resolution, you decide whether to sacrifice Overzealous Fan
• If you pay the cost (sacrifice), the targeted unit moves back to base
• If you don't pay the cost, the targeted unit stays where it is

Nuances:

• You need a valid target to put the trigger on the chain in the first place
• The opponent can respond with "Not so Fast" to counter the ability before you decide to sacrifice, keeping your Fan alive
• If targeting a unit with Deflect, you must pay the Deflect cost when choosing the target
• This works similarly to Deathgrip and Reaver's Row mechanics
