Featured Duel: Allie vs. Riley Akaba

Ayu VS Layra

Allie vs Riley

At the start of the Duel, the Field Spell Card "Sun Valley" is activated, as per the rules of an Action Duel. It will allow the players to use Action Cards, but they may only have one in their hand at a time.

Turn 1: Allie
Allie Normal Summons "Aquaactress Guppy" (600/600). She activates the Continuous Spell Card "Aquarium Stage", preventing her WATER monsters from being destroyed by battle except by other WATER monsters. She then activates the Continuous Spell Card "Aquarium Set", increasing the ATK of all "Aquaactress" monsters on the field by 600 ("Guppy" 600 → 1200). Allie finally activates the Continuous Spell Card "Aquarium Lighting", doubling the ATK of all "Aquaactress" monsters until the end of the Battle Phase when they battle another monster. Allie calls for the attack of "Guppy", but is unable to since the Battle Phase can't be conducted during the first turn. Allie Sets a card.

Turn 2: Riley
Riley activates "Shutter Layer 1", targeting a monster Allie controls and Special Summoning the former as a Normal Monster with the same name, Type, Attribute, Level, ATK, and DEF. He targets "Guppy", Summoning "Layer 1" as a copy of that card (600/600). By the effect of "Aquarium Set", it gains 600 ATK (Riley's "Guppy" 600 → 1200). Riley Sets a card.

Turn 3: Allie
Allie Normal Summons "Aquaactress Tetra" ("Tetra" 300 → 900/300). She finds the Action Card "Sunshine Smile". Allie's "Guppy" attacks Riley's, and she activates "Sunshine Smile", increasing the ATK of her "Guppy" by 400 until the end of the Battle Phase (Allie's "Guppy" 1200 → 1600). During the Damage Step, "Aquarium Lighting" doubles the ATK of both "Guppy" (Allie's "Guppy" 1600 → 3200, Riley's "Guppy" 1200 → 2400). Riley's "Guppy" and "Layer 1" are destroyed (Riley: 4000 → 3200 LP). "Tetra" attacks directly (Riley: 3200 → 2300 LP).

Turn 4: Riley
Riley activates the Continuous Spell Card "Shutter Layer 2", preventing Allie's cards from being affected by her own card effects (Allie's "Guppy" 1200 → 600, Allie's "Tetra" 900 → 300). Riley activates another "Shutter Layer 1", once again targeting "Guppy" and Summoning itself as a copy of the targeted monster (600/600). By the effect of "Aquarium Set", it gains 600 ATK (Riley's "Guppy" 600 → 1200). Riley's "Guppy" attacks and destroys Allie's "Tetra", with "Aquarium Lighting" doubling the former's ATK during the Damage Step (Riley's "Guppy" 1200 → 2400; Allie: 4000 → 1900 LP).

Turn 5: Allie
Allie Tributes "Guppy" to Tribute Summon "Aquaactress Arowana" (2000/2000). Because the monster it was targeting left the field, "Layer 1" is destroyed. "Arowana" attacks directly, but Riley activates his face-down "Instant Shutter", Special Summoning it as a Normal Monster with the same name, Type, Attribute, Level, ATK, and DEF as "Arowana" (2000/2000), but it will be destroyed at the end of the Battle Phase. By the effect of "Aquarium Set", it gains 600 ATK (Riley's "Arowana" 2000 → 2600). Allie activates her face-down "Aqua Story - Urashima", banishing two "Aquaactress" monsters from her Graveyard to make the ATK of one of her opponent's monsters 100 and prevent its ATK from being changed by other card effects this turn. She banishes "Guppy" and "Tetra" and targets Riley's "Arowana" (2600 → 100). "Arowana" attacks and destroys "Arowana" (Riley: 2300 → 400 LP).

Turn 6: Riley
Riley Normal Summons "C/C Critical Eye" (1400/1000). He then activates the Continuous Spell Card "Montage Fusion", allowing him to Fusion Summon a Fusion Monster in his Extra Deck as long as both him and his opponent control the required Fusion Material Monsters. Since Allie controls a WATER monster, he uses his "C/C Critical Eye" to Fusion Summon "C/C/C Water Sword of Battle" (2400/0). "Water Sword" attacks and destroys "Arowana", with its effect increasing its ATK by the ATK of all other WATER monsters on the field ("Water Sword" 2400 → 4400; Allie: 1900 → 0 LP).
