Takedowns as an amputee

Just a quick question. I did a competition last week and realized that I lost my chance at gold specifically because I tried to go for a takedown whereas my opponent just went into a guard pull instead. As an amputee what takedowns should I learn (because fuck guard pulling unless I have no choice). I usually try Tai Otoshi or the Tomoe Nage but this dude just immediately guard pulled once he got a grip and it killed me very quickly. Just looking for tips or suggestions for takedowns. Right leg above knee sorry forgot to include until someone kindly told me
