My personal "Plus" rule deck is designed for 7-9 range plays and works well against "Corner Defense" decks. Open with Lucia in 9, as "Corner Defense" players often avoid aggressive plays, placing a corner card near Lucia. Use Belladonna or Gilgamesh & Enkidu to plus those cards effectively. Leviathan is versatile, serving as either a plus card or a defensive corner card. Ardbert, with his 3 9s, is useful for additional power if the "Plus" rule isn't favorable.

Alternative Cards:

Ardbert → Therion
Lucia → Lyna/Hilda/Ysayle
Gilgamesh & Enkidu → Mammoth
Leviathan → Ramuh/Odin/Innocence/Shiva
Belladonna → Echinda/Brachiosaur/Grynewaht
