Gemini Fusions (Yes, that crazy deck)
Difficulty: ☆☆☆☆☆
You will win every single time without issue. Most Gemini fusions have few to no answers to Black Luster Soldier’s 3000 attack, or Relinquished.
Téa Burn
Difficulty: ★☆☆☆☆
Play aggressively and play as many cards as possible to reduce your hand size to 0. The exception is if you have the materials for Relinquished. You can save those in your hand and take control of their face down with Relinquished on your next turn for an easy direct attack. Always attack face-down monsters with Black Luster Soldier first.
Weevil Burn
Difficulty: ★★☆☆☆
Only slightly more difficult than Téa Burn. Parasite Paracide can be tributed for Thunder Dragon, which can then be subsequently tributed to ritual summon Black Luster Soldier. Always attack face-down monsters with Black Luster Soldier first.
Clowns
Difficulty: ★★★☆☆
Force defensive cards such as Desert Sunlight and Enemy Controller with Relinquished, follow up with Black Luster Soldier. Kill Guardian Statue first.
Relinquished
Difficulty: ★★★☆☆
Do not summon Black Luster Soldier unless you have Skull Lair on the field, or are sure you can play around a potential enemy Relinquished. You will outpace them and obtain additional materials for both Relinquished much faster than them when you have Gateway to Chaos active.
Harpie’s Hunting Ground
Difficulty: ★★★☆☆
Bait Enemy Controller and Order to Charge with Relinquished. If they E-con your Relinquished feel free to attack and kill it with Black Luster Soldier for 3000 damage on the same turn. Your field spell isn't really very important, but try to get 3 spell counters on it to search out a ritual spell if possible.
Shine Balls
Difficulty: ★★★★☆
Again, used the first Relinquished as bait, and follow up with Black Luster Soldier on the same turn. Use the field spell to collect another Black Illusion Ritual or Black Luster Ritual(if you have the materials to summon a 2nd Black Luster Soldier). If they have Shine Balls on the field then chain Skull Lair to Order to charge to negate the effect. Of they have a clear field and summon Venus, immediately use Skull Lair on it.
