Here is a deck to help you finish the event exclusive missions. Duel with a low-leveled Gate Legendary Duelist (You can duel Jaden/Yubel Lvl 10) or a standard duelist who doesn't have monster removals to easily finish the missions.
"Summoned Skull" + 1 DARK monster This card's name becomes "Summoned Skull" on the field, but is still treated as an "Archfiend" card. All "Summoned Skull" you control gain 500 ATK. If this Fusion Summoned card you control is sent to your GY by an opponent's card: You can Special Summon 1 "Summoned Skull" from your hand, Deck, or GY.
Cannot be Normal Summoned/Set. Must be Special Summoned (from your hand) by Tributing all monsters you control, and cannot be Special Summoned by other ways. This card's ATK becomes the combined original ATK of the Tributed monsters. If this card attacks a Defense Position monster, inflict piercing battle damage to your opponent.
Cannot be Normal Summoned or Set. Must be Special Summoned (from your hand) by sending 1 face-up "Elemental HERO Neos" and 1 face-up "Yubel" you control to the Graveyard, and cannot be Special Summoned by other ways. This card cannot be destroyed by card effects. At the end of the Damage Step, if this card battled an opponent's monster: Inflict damage to your opponent equal to the ATK of the monster it battled, and you gain Life Points equal to that monster's DEF.
EX Jewels can only be obtained from event mission rewards (event + weekly), and farming Yubel. You can not save the EX Jewels for the next event because they will expire when the EX Jewels shop closes. It is recommended that you carefully choose what to spend them on, because you can not obtain anymore after the Yubel event ends.

try my deck
1x GK vassal
1x secret rooms to treasures
3x triamid cruiser
2x triamid kingolem
2x traimid fortress
2x traimid dancer
3x triamid hunter
2x triamid master
2x triamid pulse
throw in a god if you want to boost a bit of DP
Chain a triamid on field spell for fortress when they use those destruction spells
keep fortress at the end of every yubels turns and activate dancer or master while fortress is on field to bait Ulti prov, pulse destroy yubel upgraded forms on chain link 2 to mis timing (or on lava golem), keep dancer + master and keep using dancer so the two has combined total 5k+ atk. final turn use bread and butter combo 2x union + secret on vassal and otk. probably works less efficient tho
