So I'm getting back into the game after not playing for a little bit. Last time I played I was running a pure sky striker deck, and tbh I'm good on how the deck plays and personally I love it but since I've been gone I've noticed a difference in the extra deck cards people use.

For example in this one build I looked at a build from March and the extra deck was:

• Sky striker ace - Hayate x3

• Sky striker ace - Kagari x3

• Sky striker ace - Shizuku x3

• Sky striker ace - Kaina x2

• Knightmare Phoenix x1

• Knightmare Unicorn x1

• Topologic Bomber Dragon x1

• Borrelsword Dragon x1

How was he making the borrelsword?? with only 3 raye (the rest of the monsters being hand traps)

Forgive my scrubness just looking for some help.
