Well that was all Messed up
First no land was tapped to play that creature
Second You cant even attack with that creature because at the beginning of your upkeep you have to sacrifise a creature and if that is your only creature in play you MUST cacrifice that creature and you cant regenerate it because youre sacrificeing it
Third its flying the Kavu can't block flying
This was a total waste of time Please at least read the rules before attempting to make a flash like this, because sometimes its insulting to wach. I know all you fellow MTG players agree with me.
