Burn & Evolve
Keep one Oddkin, sacrifice another. The survivor becomes a Zombie or an Alien — archetypes the mint never produced and a reroll can never reach. The sacrifice is burned forever, and nothing here can be undone.
Why this takes two signatures
Signature 1 — commit
Burns your sacrifice, pays the ODDIN, and books a block a moment in the future. The result is not decided yet, and nobody — you, us, or anyone watching pending transactions — can see it.
Signature 2 — reveal
Once that block exists, its hash decides the coin flip. This second signature reads the hash and writes your new archetype. It costs no ODDIN — only gas.
Same commit-and-reveal shape as a reroll in Manage. One transaction could not do it honestly: the roll would be visible in the very call that pays for it.
