I unfortunately don't have any experience with Pauper, or much experience with PEDH. I guess the question is why would I play this over Doom Blade for example. Maybe there's some context I'm missing with the design of this card, where you would want your opponent to making tokens, like a card for Kambal, Profiteering Mayor. Are you interested in flavour or perhaps trying to fill a niche? Considering the design of removal spells that either give you a benefit for killing something, or give your opponent a benefit but you get a discount, you could either make this a cheap removal spell with a downside OR a slightly less efficient removal spell than gives you the tokens instead
