Here's a card I've been contemplating, it's got quite a nifty effect, allowing 3 direct attacks to your opponent's life points.
It's got draw backs, first it doesn't work on effect monsters, so you can't use monsters with effects that would easily get three out, or allow for multiple attacks, or something like that
And you need three of the same monster, which isn't easily done (especialy if you want to use 3 Blue-Eyes White Dragons)
Though there are some fun combos to go with it, first of all, there's Ultimate Offering which can help you get 3 of the same normal monster out, as long as it's worth the thousand life points (if you can use Ultimate Offering for 2 extra summons in one turn, that is)
Then there's Mokey Mokey King! when...
