It seems pretty weak. Supply Squad is rarely used, and this self destructs and doesn't work in multiples. This is possibly easier to combo with, but the fact it self destructs if you don't summon something during your opponent's turn makes it just not worth it in my opinion.
5 card hand / 6 card hand
Chances of only opening 1 copy: 30.11% / 34.07%
Chances of opening 2 copies: 3.54% / 5.16%
Chances of opening all 3 copies: 0.10% / 0.20%
Chances of drawing into an additional copy with its effect when you've opened, in a 5-card hand, 1 copy / 2 copies: 5.71% / 2.86%
on a 6 card hand: 5.88% / 2.94%
As these numbers show, running three copies is perfectly fine since the odds of seeing it multiples are very low. Same goes for pretty much any good HOPT card that you want to run multiples of. You're also comparing this to Supply Squad, a card that is far more situational in how you trigger it. With Squad, you have to use typically min. 2-card combos to get it to proc, and those have to be a bit more situational and in a particular deck that also actively wants to destroy.
Special Summoning from the hand is freaking super common-place in that pretty much every deck performs at least one during a turn, only really a few that actually don't. As for the self-destruction? That's fine? Even if you're only drawing one, that's still as good as an Upstart and, as we've seen, that's still pretty good.
Ultimately it will come down to testing to determine how actually good this card is, and considering that it requires other cards to work with it is, admittedly, something that makes it a brick if you aren't opening with monsters in your hand or a means to search monsters. But in a lot of decks, that means you've bricked anyways, and it doesn't interfere with overall consistency so long as you aren't sacrificing cards that make your deck more consistent.
I wouldn't be surprised if this started making rounds, though. I wouldn't sleep on it.
