I found that it is a great idea for when you know your monster is soon to die, that you go and battle in one of the free rank battles and get a tech stone so that when your monster dies and you raise a new monster, not only will you get a tech from the dead monster's heart, but you will also have a stone to learn another move. many of you probably have already thought of this, but for those of you who haven't, now you have a new idea!

Also, if the tech matches the stone, you can give the stone and then give the heart to easily gain levels on the tech.

It's ecpspecaillay nice if you use it on arank c/b that was hibernating. that way, you cud have the next generation thoroughly trained.

can u give a monster heart to a already alive monster/
