Heavy? I was in fact thinking it was too easy. Like Kiddo says, Acid Golem on steroids. Acid is not immune, and even backstabs with the no Special Summon Clause, is only 3l [compared to this one, only 3k, otherwise a good 3k]. The only downside of this one compared to Acid Golem is that Acid Golem only requires 1 card for making it. Crane Crane, Wind-Up Rat, Tour Guide from the Underworld. But even for that, I have been thinking this card was too OP.
