If "battles an opponent monster" still counts when this card is in defense position, then you can use Sorcerous Spell Wall and raises its DEF to 1900. It's not that bad, I guess. Obviously, this only works when the opponent monster has low ATK
This is good. With a card that stops position movement (Grarl Axe ect) You can pretty much Floodgate trap hole the enemy. With Halfshut and Econ this isn't that bad in a control deck. Plus it's rock so.. Block Golem can revive it.
This card is actually bugged: I attacked it in def position with my Ryu Kokki (1600 def vs 2400 atk), it doesn't get destroyed and aslo activated his effect. In the next turn, my opponent tribute summon Horus lv 6 with that Gonogo and really tilted me. 🔥 komoney
