→Post-Duel Terminal 7
This version of the deck gives the player extra negation power using "[[Void Ogre Dragon]]", good plays for future turns using "[[Hundred Eyes Dragon]]" (especially when combined with "[[Lavalval Chain]]"), and easy monster destroying with burn damage without the risks attacking brings using "[[Infernity Doom Dragon]]". All three of these monsters also have an extremely powerful 3000 ATK, whereas the Xyz variant's strongest monsters are only 2500 ATK.
"[[Hundred Eyes Dragon]]" is arguably the most important card Synchro monster in this build. By Synchro Summoning "[[Hundred Eyes Dragon]]" while also having a "[[Lavalval Chain]]" out (which you normally will), you can use "[[Lavalval Chain]]" to send whichever monster you want from your Deck to your Graveyard, then use "[[Hundred Eyes Dragon]]" to copy that monster's effects. With an "[[Infernity Necromancer]]" in your Graveyard, you can use "[[Hundred Eyes Dragon]]" to banish it and copy its effects then gain the ability to Special Summon an "[[Infernity Archfiend]]" from your Graveyard. Then, with "[[Infernity Archfiend]]"'s search you can grab another "[[Infernity Necromancer]]", and Normal Summon it, then activate its effect to Special Summon "[[Infernity Avenger]]", then Synchro Summon into another Level 8 Synchro. Also, you can search more "[[Infernity BarriersBarrier]]" s via this combo too. You can also use "[[Hundred Eyes Dragon]]"'s effect to copy "[[Infernity Mirage]]" instead. By tributing himself to Special Summon "[[Infernity Archfiend]]" and "[[Infernity Necromancer]]", you can gain another "[[Infernity Barrier]]" and a different Level 8 Synchro.
Also, since you will normally have a Level 4 monster out, "[[Infernity Avenger]]" can resurrect himself as Level 4 if that monster gets destroyed, and make another easy Level 8 Synchro play then next turn, and the 1 "[[Infernity Avenger]]" is easily ressurectable via "[[Infernity Necromancer]]".
