Question

If Fabian Cortez’s “When Defeated” ability puts an Acolyte minion with the teamwork keyword into play while Fabian Cortez is the only other Acolyte minion in play, will the teamwork keyword on the other minion trigger?

Answer

No. Since putting the other minion into play is the last effect of Fabian Cortez’s “When Defeated” ability, he is discarded immediately upon the other minion entering play. This means Fabian Cortez is no longer in play when the other minion‘s teamwork keyword tries to find an Acolyte minion in play.
