6) Tune "Fire Ant" with the Level 5 "Quilla" and Synchro Summon "Sun Dragon Inti".
"Limit Reverse": This trap allows you to Special Summon a monster with 1000 attack or less. "Oracle", "Fire Ant" and "Supay" all have under 1000 attack, so this card can be used to revive the monsters and use them for more Synchro Monsters.
"Skill Drain": This card shuts down all monster effects for the cost of 1000 life points. This card counters many decks in the current meta. Also, the Dragon's effect activates in the Graveyard, so it will not burden the deck.
Inti and Quilla are most likely paired up and given the ability to revive one another because Inti, the sun god, was married to Mama Quilla, the moon goddess - this is symbolic of the way day chases night, and vice versa. "Earthbound Immortal Wiraqocha Rasca" is also based on Viraqocha, the god of everything in Incan culture.
Out of all the Incan monsters, Ascator is the only one that isnt based on a figure of Incan mythology, rather its based on Azcatl of Aztec mythology.
