Yeah, N-to-1 is getting old...
But, correct me if I misread this:
Once N leaves, if N leaves(assuming SUM-On), Ilima will take his place as the next hand disrupting staple... And, in case you want the opponent to feel more misery than just flipping tails and drawing 3 cards after, then...
...One can combine Ilima + opposing tails w/ Tormenting Spray, so that your opponent has a possibility of going down to two cards, AND no draw supporter, in hand to salvage his/her following turn... If two tormenting sprays are used to discard two supporters from opposing hand, that will be the equivalent of an N-to-1 that's potentially worse than N-to-1 itself, due to the victim's bad luck on the Ilima tails to cut his/her hand down to three, then having to discard potentially all of his/her draw supporters in hand depending on the Ilima-using player's choices of cards from his/her opposing hand. Seriously, in such a fashion, having no draw supporter in hand at the start of your turn, and failing to top deck any draw support means you're forced to either use Oranguru SUM ability to hopefully get a draw supporter, or, if you fail to do so, an emergency Lele put-down to get a draw supporter from deck, or if you're unlucky enough to have zero access to lele/draw supporter, assuming the Ilima+spray user is down to 1 prize card or two, either concede or face the Guzma for the loss. But in the event the Ilima+spray user has 4 or more Prizes remaining, pass and hope the opponent does not have a means to get one more chance for him/her to turn the battle's tide so that the loser becomes a winner...
^ Just because N is due for rotation if he isn't revealed in the August set doesn't mean players can rejoice with a guarantee of at least 3 cards outside of self-inflicted causes just yet: People could flock to N-to-1 substitutes such as Ilima+Spray for the chance of an equivalent effect...
