How annoying would this be? It's great with
Smokestack at the very least

Seems perfect if you hate red.
I don't think it's actually very strong, as it makes 0/3s, but it basically beats an entire archetype on its own, which is problematic.
You could probably get away with a 1/1 or maybe T: Create 1/1 is a bit better. Then it compares to a lifeless grounded Bitterblossom with a mana option at 3mv. Still very annoying if your aggro decks rely on 2/1s, however.
It's pretty interesting with the current effect, but making a 0/1. Nearly worthless tokens that encourage the player to sacrifice them in order to get more value. That said, maybe that's a Kobold red card? Or a black Serf card? Something where the colors are more likely to be sacrificing. Maybe it's fine as a blocker for control.
It's worth noting that the original white, blue, and red designs are pretty playable by any deck, whereas the black design feels like it's considerably more likely to get value in Bx.
Also worth noting that the red one is able to make any color via the treasure, while the others are not. I personally would prefer to see them all make any color in order to expand their playability as well as possibly changing the black design to be more universal.
