Infernoid Onuncu is the boss for its Deck, as you probably gather if only by looking at the card.  Take a second to do so, and just be in awe of that artwork.  3000 attack and defense...spectacular, Fiend, and Fire (odd but works) and Level 10 is fun.  So you can't Normal Summon or Set this card, and it MUST be Special Summoned by removing three Infernoid Monsters from your Hand or Graveyard (not and/or, simply or) while you control Effect Monsters whose Levels and/or Rank are 8 or lower.  Now, once Special Summoned, you destroy all other Monsters on the Field, so there's a plus, and it probably would be wise not to have anything on your Field just so you don't lose anything.  Once per turn (during either players' turn) you can negate the activation of a Magic/Trap card by Tributing one Monster on the Field.  Infernoids are quick, they like to swarm, but any Deck that can shut down the removal mechanism is going to slaughter this Deck.  You're running two of these I'd say in the Deck, he's a beast.

Hello Pojo Fans,
 
Infernoids are an interesting archetype, packing one heck of a boss monster: Infernoid Onuncu. All “Infernoids” have the same Type, Attribute, and roughly the same kind of summoning conditions.
Onuncu needs 3 “Infernoid” monsters banished from either the hand or grave to be Special Summoned,  with the added restriction of effect monsters on your field not totaling over 8 stars/ranks.
 
Monsters with the text “cannot be Normal Summoned/Set. Must be Special Summoned” usually cannot be Special Summoned from the graveyard. This card can be Special Summoned from the hand and can pull itself out of the grave with its effect. Once on the field, Onuncu will wipe the field clean of monsters. Tribute a monster on the field and Onuncu can negate a spell/trap during either players turn. The monsters don't need to be “Infernoid” or Effect monsters, it can be any monsters or Tokens you control. Spell/Trap negating and the ability to pull itself out of the graveyard, Onuncu is a worthy boss monster.
 
Infernoids need to have access to other Infernoids to banish to Special Summon themselves. Cards like Reasoning, and Monster Gate can help fill up the graveyard for a swarming of the field. Necroface can return the cards to the deck to be used again, and Infernoids have their own spells/traps that are archetype-focused to help ease their summoning conditions.

Infernoid Onuncu

Onuncu is the big Infernoid boss monster, and when I say that he’s big, I think it’s fairly obvious I’m not exaggerating. 3000 ATK and DEF is huge, especially when combined with Onuncu’s own very potent effects. Even though destruction effects aren’t that great, Onuncu’s is still pretty potent – it doesn’t target and hitting everything at once is still pretty solid. The effect that destroys Spell and Trap cards is also pretty decent, it goes along rather nicely with the rest of the disruption that the Infernoids have.

The main issue, from what I can see, is that Onuncu is rather difficult to use potently due to it pretty much always having to be the only Infernoid monster you control. If you summon another before it  you can’t use the destruction effect and attack with both, it’s a minor issue, but still not really what you want. The other thing is that Infernoids are incredibly inconsistent, and are hurt by floodgates way more than any competitive deck should be, Onuncu has the issue that all of them have – they’re great when the deck gets going, but… well, the deck doesn’t get going often enough.

Rating 3/5
