Tenyi Yang Zing (TYZ) is a deck that's main focus is on card advantage. Card advantage is how TYZ is able to get a leg up on other decks and overwhelm them Non-effect monsters and synchros. The main play of the deck is to use one of the 3 one card starters (Souleating Oviraptor, Draconnet, Mathematican) to synchro summon Denglong and search Nine Pillars (Pro tip don't set backrow until you search Nine Pillars to ensure your opponent doesn't know where you set it). Then afterwords, use Denglong's effect to send a Tenyi from deck to GY (the best one to send, most of the time, is Ashuna) (BTW the level change isn't that important). Then on the opponent's turn negate something with Pillars and off of denlong being sent to GY summon Bi'an, then you revive Denlong with either Buddy Force or Back to the Front, use denlong to search Yang Zing Path (for card advantage), and when you see an opportunity use Bi'an to synchro with Denlong into Baxia and shuffle 2 cards on the opponent's field (Pro tip don't chain Bi'an to a card effect because if you do Baxia will miss timing, also Bi'an gives Baxia battle protection). That's the main bread and butter combo of the Deck that's a +2 in card advantage and gives you a way to recycle the Yang Zings (and draw 2) and puts a Tenyi in the GY.
