Elements Unite! You will start the duel with 500 Life Points and your starting hand will be 1 card, which is "Gate Guardian". In addition, you will start the Duel with Suijin, Kazejin, and Sanga of the Thunder on the side of your field. Their effects are negated and they cannot attack as long as they are face-up on the field.
The biggest threat to this deck from Rex 40 is his Solidarity + Jurac Impact. Acid downpour removes all other direct threats against Gate guardian, but Rex can pop Solidarity, to get another dino with 2500 atk, then can use Jurac to wipe the field. Recommend removing 1 pathfinder, to add 1 trap (spell purification, or wild tornado) to remove Solidarity as a threat...
Also, even if you have Acid downpour active, make sure you trigger pathfinders effect, makes the duel faster..
Ran into a situation, solidarity had already been dis-enchanted but he he was able to summon his super-ancient dino to the field. Acid downpour was active, but super-ancient was 2500 atk, so Rex could and did pop Jurac when I attacked super-ancient...
I have only seen him pop Jurac when he's being attacked, so adding trap jammer just in case should get rid of Jurac threat.
Can I replace Gravekeeper's Vassal and Union Attack for Piranha Army, Riryoku, and Gift of the Martyr?
