After the support, Evolsaur goes from a horrible 3 turn combo deck into a Xyz spam deck.
*The main idea is to use "Evolsaur Phoris" to summon "Najasho" from hand or GY.
THen you use the second effect of phoris to get "Evo-Diversity".
Then tribute "najasho" with "Evo-diversity" to summon two "Evolsaur Rios" from your deck, one with "Evo-Diversity" and the other with "Najasho".
THen you use the "Rios" summoned with "Evo-Diversity" to set a "Evo-sigularity".
From this point, you should have two "Rios" and 1 "Phoris" on the field. This allows you to go into any of your rank 4 monsters, or rank 6 monsters using the "Rios" second effect.
The hand traps that I'm playing are in the deck because of the way the can interact with other hand traps. They can be switched with other hand traps or for going second staples like Dark Ruler.
The ogdoadic monsters work as combo starters, extenders, and Combo pieces, depending on the hand. You may want to change ratios if you want the deck to be smaller.
The evolsaur monsters are in there for certain combos using the ogdoadic monsters as starters. They can be cut if you are not playing the Rank 6 monsters or are alright with less versitile end boards.
