Very good. For decks that don't use monsters with a lot of attack, this card can make or break the game.

To the guy saying he is the best synchro. He is not. Brionac and Scrap Dragon are by far the best synchros out. They can both clear either backrow or monsters without attacking... in the meta, having to attack is very risky. Not to mention, usually, the best monsters out, are dark to begin with. He is good no doubt, but definitelly not the best.

This is the best Synchro EVA! its ability to destroy anything that isn't DARK attribute is mind huffing. combine this card with DNA transplant and its basicly almost invincible. Get this card and put it in a spell/trap zone lockdown deck and then he's beast

Reasons Why This Card Is A Must Have: 1) Easy to Sync 2) Awesome Effect 3) Works Very Well With Alien Decks

  -- By Eddie Landry from Shreveport,LA USA on June 22, 2010

Must have for every extra deck, Especially Blackwings. They are so ownage with this card. And there can also be situations where you have a blizzard in your hand and a kalut in the grave. What do you do? you summon blizzard, Revive Kalut, then Synchro for this guy. Not only is his effect good, he can take down big beatsticks.
