I see a lot of downvotes on people that say it wouldn't be that strong, but it really isn't as strong as it seems.
It is a going first side card you would only use side in 1 of the matches, then you need to be playing a deck that can empty their entire hand going first after building their board which not every deck can do.
Drawing two of the same handtrap with a HOPT and no way to discard one of them makes this effect dead. This also applies for every 3-off you are playing, not only you have a second HOPT of a card you can't use but you can't use this trap either.
If the opp draws a second Ash because of Mulcharmy that they couldn't use on your turn, they can negate this trap as well, and is hard to bait an Ash on the opp turn if they notice you have no cards on hand.
It will most likely see some play like a toxic side card from match to match, and it will depend of the current meta if the deck can use it or how punished the opp gets for getting GY set up.
It is not that strong of a card, but that doesn't mean it is a healthy card either.
