Why this card got banned the second time around instead of the first I do not know. This card is just that damn good that it should have been banned the first time around.
Back in the old days Change Of Heart with a tribute monster in your hand like Jinzo meant good game. Awww the memories. I would use this wonderful card to take an opponents face down Magician Of Faith, flip it, get back COH, and sacrifice it for Jinzo.
It's rather sad though how that will only be a memory. With it's friend brain control this card will get no burn. It's rather sad actually. Oh wellZ we can all remanise I guess.
