this deck were used from gold V to diamond III, after that i decided to cut the DPE engine since most of the time I drew celestial or dasher, not the fusion destiny
for the decklist i used to diamond I : https://ygoprodeck.com/swordsoul-tenyi-9/

Basic Combo:
1 Card:
Swordsoul Emergence
search for taia, banish taia, search for swordsoul emergence (if you drew wyrm next turn, you can search mo ye, if you did not search for taia) or swordsoul blackout (for extra disturption).
2 Cards:
Swordsoul Mo Ye +1 wyrm
bread and butter of swordsoul combo, mo ye would synchro lv 8 chixiao to search for Longyuan and synchro 10 (either baroness or chengying, if you have card effect that banish or destroy your chengying except chixiao such as called by the grave or swordsoul blackout) chengying could be solid option.
2 Tenyi
(Ashuna +1 different name Tenyi)
Special summon ashuna, link summon monk tenyi, use the second tenyi to SS itself, use ashuna effect to SS the different name from field tenyi (i.e. SS vishuda if you have adhara) synchro to chixiao.
Now, you have two route depending on your hand and matchup, against light based opponent, you don't want to banish adhara since you want to use baxia eff to destroy monk of the tenyi and SS adhara.
route 1:
banish Adhara to add Ashuna from banish, chixiao would search for Mo Ye or Longyuan, Mo Ye will reveal ashuna to synchro lv 8 (baxia or drago berserker of tenyi) or longyuan would discard ashuna to become chengying.
route 2:
Chixiao search for Taia (no wyrm or swordsoul) or Mo Ye (have another wyrm / swordsoul card), synchro lv 8 baxia then destroy monk of the tenyi to SS adhara from GY, synchro 9 chaofeng lock light
4 card:
the combo is pretty similar with 2 card Mo Ye, but you start with Longyuan first to synchro baronne to avoid nibiru, then you will synchro Baronne, then lv 8 chixiao, alternatively you can do this with taia for three hand combo.
Archnemeses Protos:
generally not first turn card, except you know you will fight against PK or dark attribute based deck, also a good counter for DPE since it could not be destroyed, would destroy DPE and lock DPE from special summoning. However you either hard draw or have wyrm synchro still on the field to actually search this card with swordsoul emergence. You might tempted to destroy your own chixiao if you know you will fight against light attribute based deck.
