Lyrilusc OTK

The strategy is to get as many materials as you can for Assembled Nightingale

 

There aren't really any set combos; since the deck is smooth. If you need combos then

Fraktall discard Sparrow

Warbler or Canary into Sparrow (Canary preferably)

Sparrow search Sapphire Swallow

If you have Jack-In-The-Hand, or Where arf thou, then search Warbler(if step 2 was with canary), Kinka-Byo, or Slower Swallow with Jack-In-The-Hand, if you have Where arf thou then just search Warbler, you'll want Warbler every time if you can't get Warbler then get Slower Swallow

Xyz Summon Recite Starling in your extra monster zone

Recite Starling effect, search Wagtail

Activate Swallow to special It and Warbler(If you can still use Warbler's effect from hand if not special Wagtail, and skip the next step.)

Activate Warbler to special Wagtail

Have Wagtail search Bird Sanctuary

If Slower Swallow is in hand then special it

Xyz summon Assembled Nightingale using 3 or 4 materials

Use Sapphire Swallow's material effect to add the material detached from starling for her effect

Use Assembled Nightingale's effect detaching Wagtail

Use Wagtail's graveyard effect to add it back to Assembled Nightingale as material

Activate Bird Sanctuary

Use the effect to add Starling and its material to Assembled Nightingale

draw 1 with Bird Sanctuary

If you somehow topdeck Xyz Import and your opponent has a low atk monster on their field activate it and add it to Assembled Nightingale

direct 6-8 times for otk (ik 6 isn't usually otk but if canary is added to Assembled Nightingale it is due to the +200 atk)

the atk would be 1400-1800 with 6-8 direct attacks + Assembled Nightingale can't be destroyed by effects or battle

if you can't otk just activate Assembled Nightingale detaching Wagtail at the start of your opponents next turn
