I apologize for not linking, dunno how to do it on this app (just joined), but say if I play curse of the nightly hunt on my opponent and he has sentinel gargoyle and during whichever turn when the attack phase is initiated and my opponent has 3 land available, would he have to use his land to use sentinel gargoyle's ability to lose defender and attack me?
Link by putting the curly brackets around the cards name -{Curse of the Nightly Hunt} {Sentinel Gargoyle}
No. He would be required to attack with all creatures capable of attacking. If it has defender, hes not obligated to animate to attack.
Okay, thanks!
