I used a very similar deck for the bonz event, works great. 8k easy. Suggest using Dim-Gate on your lab wall asap, then use massive morph on any monster who gets their atk near / over 3k. The AI will often set a massive morphed golem to def mode, so make sure you set it to atk mode before using UA.
First use Massive-Morph into on of his powerful monster. Now use E-Con and tribute your Lab-Wall to gain control of that powerful monster. Summon Vassal and you know then.
What this op didn't tell u guys: if first two turns no dgate, he might zero gravity and u lose. Following 2nd turn onwards, if you still don't have acidic with you, his golem summoned and u lose. This deck is not really that consistent as what he said.
It is that consistent! You just can’t use it properly! I won 19/20 with this deck! You can switch Jar of Greeds to Good Goblin Housekeepings but it is probably the best deck to use!
