Yubel Is Good or Bad

Ok guys vote.

If anyone dosent know what Yubel looks like. Here you go:

Seems kinda like a trade-off to me. You wouldn't want to use this unless you were ahead in life points. And even then that depends on the monster you tribute each turn. if you have this plus some other really powerful guys out, I'd say it could be effective. It'd also be a good way to end a duel, since your opponent takes damage before you.

Well theirs good and bad sides to Yubel though.
