Wow that extra deck is cancer too me.
You don't play any no effect extra deck monster. Add Scrap archfiend and take out Armades for it. Take out Leo, Kepper of the sacred tree for a Gaia, the force of earth.
You should take out the Star Eater since you will never really want to go into him anyway (I've played Infernoids so much I've never wanted to summon him while I played him)
You need too add Gem-Knight Pearl and Daimond Dire Wolf. I suggest 1 taking Star Eater's spot and the other one takes Felgrand's. The reason you want to play the no effect extra deck monsters is so you can push for otks easier since you take lvl/rank of the field who counts towards Infernoid's summon.
In the side deck you should make room for Jinzo as he can be summoned of Reasoning and Monster gate than just luck a sknight player out of the backrow.Also Spell canceller can auto win vs Necloths since they cannot play spell cards.
Take out compuls just because the card is just purely bad at 1, replace it with a Book of moon insteed as it works the sameway and faster alot of the time to like get a Vanity's fiend of the board.
You should put alot more into side deck backrow hate, fairy wind is a card I think you really need to play since it's a really good card vs truble some matchups because of floodgate cards as: Skill Drain, Lose 1 Turn (Infernoids have barely any deffens), Necrovalley, Vanity's emptiness, Macro Cosmos, Dimensional Fissure and more.
Also having alot of Djinn outs is important since you just losse to it and Necloths can open the combo alot also the djinn outs also work in game 2 to get around Vanity's fiend and such.
If you want more help I'll be gladly here to help since I played Infernoids and have a good understanding on how they work.
btw last note, ADD ANCIENT SACRED WYVERN TOO THE EXTRA FFS IT'S THE OTK WIN CARD! And you should prodably cut 1 of the lvl 1 Infernoid for another Harmadik or Patrulea.
