Creative Deck Profile: Mysterune of Umi Danger!, Kairyu-Shin! ft. TAMA Support

Make a splash with the banish mill theme.


Strategic Summary:

Welcome back to another profile, this time sinking to the depths with two themes from recent side sets combining forces. First up is the Mysterune, an archetype centered around Spell cards that generates absurd card advantage through the effect of its Field Spell, Spring of the Mysterune (YGOrg Translation). Whenever you activate a Mysterune Quick-Play Spell, it allows you to return up to 3 from your GY into the deck to draw that many cards. It just happens to work perfectly that the Mysterune Quick-Play Spells can also choose to Special Summon a Mysterune Fusion Monster from the Extra Deck as well as their primary effect, as Huginn, Wings of the Mysterune (YGOrg Translation) ensures access to the Field Spell while Muninn, Wings of the Mysterune (YGOrg Translation) gives you access to Deceit of the Mysterune (YGOrg Translation) to allow for even more banishing of your opponent’s deck. Either way, these Fusions must discard a card to activate their effects, fueling either Spring or the Danger! monsters such as Danger! Nessie! or Danger! Mothman!

Speaking of Dangerous monsters, that’s where the Umi side of this hybrid build comes in. Led by Ocean Dragon Lord – Kairyu-Shin, the latest batch of Umi support has given the theme quite a few strong controlling effects. Kairyu-Shin itself prevents both players from having more than 1 non-WATER monster while Umi is on the field, plus it has an ability to search Sea Stealth Attack or Sea Stealth II to ensure you always have access to a copy of “Umi”. To ensure consistency to the Ocean Dragon Lord, Fish Sonar just exists, and you’ll love Tribute Summoning him using a Mysterune Fusion, as that also clears up your Extra Monster Zone for another Mysterune Fusion’s Special Summon. Beyond that, you can also turn to the Umi package for Electric Jellyfish to prevent Spell or monster effect activations and Doom Kraken for spinning and ATK negation. The depths of the Spring awaits you – just dive right into Danger!
