Hi,
again asking about the interaction of Bayushi Tsimaru Exp. and his negation of the cost for Stay Your Blade.
Alterations to costs and payments If any specific payment of a cost is negated, delayed, or made impossible in the process of paying costs, the player paying the costs may use alternate available sources to pay that cost, or may choose not to.
Can the "alternate available sources" be to send home the same target personality home again, after Tsimaru negates his 1. movement?

No.
