I need help with Elementsaber Solo Duel

I got past the elementsaber gate, and the duel seems borderline impossible. The blurb on the duel talks about some card named "Grandsoil" and a rat, but those aren't in the loaner they give you. The loaner is a completely different deck full of largely useless Wind Beasts that dont seem to synergize at all with the Elementsaber cards. It took me around 40 retries to get a usable hand, and the second I finally got ahead and my opponent had no cards in hand or board, they top decked their field spell and summoned Grandsoil, then link summoned black luster. Afaik there are no answers in my deck even with an ideal hand to a combo the AI can do seemingly easily. Is there a trick to this?
