Probably u wonder why i have only 3 onomat monsters? - no, i don't have 3, in total i have 7 onomat monsters and 1 pot of prosperity.
The strongest cards in the deck are Ascended/Armed sage with utopia double because they trigger chain link, that chain link makes cards such as veiller useless.
Important: Zs Utopic Sage is very risky to be played because is easy target for negate and u would end on very weak board if he is negated, that's why i use him in specific combos such as onomatopaira + both ascended armed sages, because the strategy is good enough to withstand negates in the process and make a good board, even if utopic sage was negated.
Why i don't play utopic future draco? It takes too much space, i need to risk playing zs utopic sage too, the strategy to play draco can't withstand negates in the process so is risky and the board i would have if i play draco is: dragonar + leo equiped + number 38 + draco.
If i don't play Draco, my board is: Dragonar + leo equiped + number 38 + abyss dweller, i consider that stronger board, i have extra space too and the strategy to make that board is much safer and even it can withstand negates in that process, so competitively speaking i don't need draco.
NOTES:
For combos such as onomatopaira + armed sage, the most people are going for zs utopic sage because they want to get to dragonar, i know dragonar is powerful but is safe to go for him with ascended sage , not with utopic sage, to try to get to him with zs utopic sage is VERY HIGH RISK, one negate from the opponent is enough to make u lose the duel, so don't do that, it's too risky !
Instead, if u have combo: onomatopaira + armed sage, go for board: Leo ray both equiped tornado and pegasus + Abyss dweller, the strategy can withstand negates in the process and is not risky, the board is also good, keep in mind in the main deck is 10 quick-play spells/traps for going first to make the board even better.
About Dragonic ray, the most of the players doesn't know how to play him, if opponent succeed in negating utopia double then u can summon in his turn dragonic 5000ATK, if the opponent target him u can either support him with pegasus or either make him not targetable by tornado, it's hard combo to deal with, if the opponent doesn't have card like droplet then he need to use his entire hand to counter all of that.
Utopic future slash + downerd magician are used for ZEUS with 6 materials, yea, Zeus with 6 materials is crazy powerful and is worth it, if u combine it with the board breakers/forcing negate cards that i have in main deck, there is no board that i can't break.
The side deck is used a lot, deppending if i am first or second, mystic mine can be either target for crossout or u can use it as board breaker going second, u need just 1 utopia and attack with 10000-12000ATK to win the duel.
The cards that can make utopia deck to lose are nibiro and droll, so for going first i have crossout with called by grave, ash blossom is not a big problem but i have it just in case as both target for crossout and as interuption.
the deck can be rebuild in budget version, the expensive cards are just the board breakers /defensive/ forcing negate cards, so there is option for budget too.
there is many combos , but i am lazy to write more
