Bird Up was the pet name MonoBlueTron's community came up with back during this deck's peak popularity. The deck didn't last long, however, as a key piece to make the two archetypes work together in Lyrilusc - Recital Starling soon got limited, as well as one of their boss monsters Simorgh, Bird of Sovereignty rightfully so got banned. With access to their omni negate in Mist Valley Apex Avian or floodgate in Barrier Statue of the Stormwinds removed the deck shortly after vanished into obscurity..
As of December 2022 however we did see some change. With the new banlist Konami put Recital Starling back to a Semi-limited status, allowing the deck's main combo line to be sort of revitalised, along with a couple of new tricks you can pull off! Scareclaw Light-Heart is a great extender, turning any tri name into ferrijit, allowing you to extend further plays and gives you more options with a properly summoned link 2 to reborn with either Spright Elf or to use as link material with Tri-Brigade Revolt .
Personally I'm not quite satisfied yet with the extra deck and the main deck flex spots. For now I put in board breakers in order to go second, but these can easily be replaced by something more fitting for your locals scene. Pot of desires is also definitely not going to stay when kashtira gets their new support.
I hope you try out the deck and if you have any ideas or feedback feel free to let me know!
