*budget options*
If you don't have the money for skill drains you can just play another handtrap like veiler or crow. Tenyi synchro also got a lot more expensive since release, you can swap it for Yang Zing Baxia.
*about the deck*
The deck is pretty linear, just use Ashuna and Adhara to get the pluses, protect the big link 3 guy with other tenyis and stun with traps. All tenyis can SS themselves from the hand, which makes them really hard to stop. They are consistent with a low ceiling which makes them perfect for casual play. If you'd like to play them on a competitive level, I recommend pairing them with Swordsouls.
