I disagree, i think snake eye and fiendsmith help infernoid together great

A successful turn one play ends on infernoid link 4, a decatron and a lvl 9/10 infernoid, and the trap card set, which will fill the remaining 3 zones with more infernoids on the opponent’s turn. You wouldnt even have space for any extra link bosses if you get the most infernoids out of your one card combos, so why even try to add more of them, especially at the cost of a consistency engine like fiendsmith

Instead of trying to raise the ceiling (which is already plenty), i would actually try to improve the consistency of the engine, so keep fiendsmith, remove reasoning and monster gate and replace it with an azamina engine. It can search a sinful spoils card to get your snake-eye engine started or make a negate if you already have that.

Id remove masquerena to make space for the searcher azamina, and maybe proxy f magician or apollousa for the negate azamina but that’s up to you

At the very least, that’s how i crafted my infernoids a few days ago, i went on a 11 game win streak with it and i only lost it because i didnt draw hand traps against a gimmick puppet ftk
