The main knock against your hand that you didn't even mention is that your hand doesn't apply any pressure; even if you draw mana, you are going to give your opponent a lot of draw steps to find their counter-hate. That being said, it is true that you do have a lot of live draws: (a) any mana source or (b) any 1cmc cantrip or (c) any one of the other 4 sideboard cards that you haven't drawn yet. That is probably more than half your library.
I think this is actually a very close call and I wouldn't fault you for throwing it away, but I think given how live the top of your deck is, and how you have a StP to interact with their plan B of an early Hollow One, I'd probably try it. Depending on your exact list, you're probably like 75% or better to find a relevant draw in your next two draw steps, and this hand + any relevant card feels like a keep even if it's slow.
