This is the best deck at doing what it does best, it knows what it wants, and it knows how do it. Ringowurm, the Dragon Guarding the Hundred Apples is a helpful addition to this deck as every Synchro this deck would run, except maybe Icejade Gymir Aegirine, require generic tuner materials. So even if you open Swordsoul Strategist Longyuan and a Wyrm + Ringowurm, you can activate Longyuan, discard the Wyrm, Special Summon the Token, then you can Special Summon Ringowurm from hand, and make Swordsoul Grandmaster - Chixiao and search!
Ringowurm and Accel Synchro Stardust Dragon allow this deck extend even better and make going into your Level 10 Synchros that much easier. This deck is fairly linear, but very effective and extremely powerful, and is still a meta threat, even after all this time.
