Sadly, unbelievably, still bugged with no ETB despite paying Kicker.

Board was: no relevant creatures, my graveyard empty, opponent's single card in their yard is Cultivate which I wanted to copy.

This is probably bugged if either graveyard is empty. You should of course still get a trigger because these are independent triggers.

This card used to work fine when it first appeared.

Still bugged as of this posting. Played [Nantuko Slicer] with kicker. Opponent had [Stone of Erech] in play. They exiled their own graveyard in response and it also denied me the ETB trigger to return something from my graveyard to my hand.

I figured out what triggers the bug. It always happens if you kick Nantuko Slicer while opponent's graveyard is empty.

I had the same thing, Nantuko slicer with kicker only one creature in my graveyard, ennemy had eldest reborn on step 2. I cast it to remove the only creature in a graveyard (mine) and it does nothing. So the game is totally screwed, will you repay my entry to the event?

Same happen to me, I kicked the card and nothing happened

kicked nantuko slicer, opponent had zero cards in yard, I had, the ability did nothing. It should let me take a card from my yard, as both are targeted abilities.
