【Touhou Lost Word】Remilia EX (E9) - Clear in 7 Turns

There's a lot of things I could say about this: 7 barriers are dumb, Daiyousei core and potent, sorry for another E1 Sakuya strat, etc.

✦ The Strategy ✦

T1. Sakuya and Miko use spread shots. Daiyousei uses SC2. Everyone grazes twice.

T2. Sakuya uses SC2, Miko and Daiyousei use SC1, everyone with full boost targeting Flandre. Sakuya uses all her skills, Miko uses skills 1 and 2, Daiyousei uses skills 1 and 3. Everyone grazes once. Flandre should now be gauge broken.

T3. Sakuya uses SC1, Miko and Daiyousei use SC3 on Flandre, everyone with x3 boost. Miko and Daiyousei use their remaining skills.

T4. Sakuya uses SC4 with x3 boost on Flandre. Miko and Daiyousei switch out with Jo'on and Reimu respectively. Jo'on uses SC2. Reimu uses SC2 with x2 boost. Reimu uses skills 1 and 2. Remilia and Flandre should now be gauge broken.

T5. Sakuya uses SC3 with x2 boost. Jo'on uses all her skills and LW with x3 boost on Flandre. Reimu uses SC4 with x2 boost. Reimu uses skill 3.

T6. Sakuya and Jo'on use shots. Reimu uses LW with full boost. Remilia should now be gauge broken.

T7. Full Auto.

✦ Notes and Hypothetical Unit Substitutes ✦

✦ Although I highly recommend maxing out Sakuya and Reimu, it may be possible to do this strategy without both of them at 5☆, but their damage may vary and you will need to cover for that with stat sticks.

✦ Yes, Daiyousei needs 2 max limit broken WoSDs for the gigachad 12 metal breaks in total. However, the WoSDs don't need to be fully enhanced.

✦ Miko can be replaced by the following units who are able to fulfill the same Sun and Metal breaks as her. However, these units will need to follow slightly different steps than Miko.

• Aya Shameimaru (A9 / PoFV)
• Shou Toramaru (L1)

T1. Aya / Shou uses SC2 equipped with a 1.5P minimum story card targeting Remilia, no boost.
T2. Aya uses all her skills / Shou uses skill 1 and 2 only. They should have 3P minimum now. Aya / Shou uses SC1 equipped with WoSD targeting Flandre with x3 boost.
T3. Aya uses SC3 / Shou uses SC4 or LW targeting Remilia with x3 boost. Shou uses skill 3.
T4. Aya / Shou switches out.

✦ Jo'on can be replaced by any of the following units who have at least 4 metal breaks on a spell card or Last Word. These units also have helpful buffs/debuffs of their own.

• Kanako Yasaka (A10 / MoF): SC2/SC4 and LW at 3P
• Sagume Kishin (B3 / Azusa): SC2/SC4 at 3P
• Nazrin (L1): LW at 2P
• Shizuha Aki (L1): LW at 3P
• Youmu Konpaku (A7 / PCB): SC1/SC3 at 3P
• Suwako Moriya (A10 / MoF): LW at 2P
• Parsee Mizuhashi (L1): SC2/SC4 at 2P
• Ran Yakumo (A7): LW at 2P
• Koakuma (E1 / Compendium of Advanced Magic): LW at 1P
• Momoyo Himemushi (L1): SC2/SC4 and LW at 3P

Whoever you use will likely need to use the turn they switch in getting to the minimum Spirit Power needed, so the 1.5P story card setup still applies. Reimu's switch in covers the remaining 0.5P for that unit and Sakuya, which is why Sakuya also has a 1.5P story card.
