I fixed it and this is the proper tx, I'm pretty sure:
0100000002d89522f8fecdd0832e69909af360551db3810deb2ad7e72a096058dcbe8f2ded0000000000ffffffffd89522f8fecdd0832e69909af360551db3810deb2ad7e72a096058dcbe8f2ded0100000000ffffffff01382d0000000000001976a914fc11decd0e0ab7a332459314069c027328e1dde188ac00000000
Yeah, UTXO you try to spend (based on new raw TX) is recognized by several Counterparty explorer. See those,
https://www.xcp.io/tx/ed2d8fbedc5860092ae7d72aeb0d81b31d5560f39a90692e83d0cdfef82295d8https://www.tokenscan.io/tx/ed2d8fbedc5860092ae7d72aeb0d81b31d5560f39a90692e83d0cdfef82295d8Now I've graduated to the next error: "RPC error -26: bad-txns-nonstandard-inputs"

I guess I need someone running a custom version of Bitcoin to push the transaction through for me...
For different case of non-standard (but valid) TX, what you need is miner who're willing to to add such TX. Other pool may do it if you contact them, while MARA currently being the only one who offer such service (MARA Slipstream) in automated way.
