Special summon Gate Guardian to stall the duel, and make sure to draw Acidic Downpour early so that you can rest easy for the remainder of the duel. Gravekeeper's Vassal would need 3 Union Attack this time if the only other monster on your side of the field would be Gate Guardian, or you can just use special summon another monster and use 2 Union Attack.

You will start the duel with 500 Life Points and your starting hand will be 1 card, which is "Gate Guardian".

Their effects are negated and they cannot attack as long as they are face-up on the field.

How to use

Gate Guardian

Special summon Gate Guardian immediately at the start of the duel. Rex would not be able to do anything about him until he has Jurassic World, Solidarity and Super-Ancient Dinobeast on his side of the field.

Acidic Downpour

Use Acidic Downpour as soon as you get it. It is important that you activate it before Rex has Jurassic World, Solidarity and Super-Ancient Dinobeast on his field, otherwise you are sure to lose the duel. Use Planet Pathfinder to help you search Acidic Downpour or use draw cards to try and get it.


  • Use draw cards to deck out quicker than Rex and finish the duel earlier.
  • This will also help you get Acidic Downpour if you didn't draw it earlier in the duel.
  • Prioritize returning last turn cards to the deck when using Good Goblin Housekeeping.
  • Do not activate Shard of Greed if you have less than 4 cards in your deck.

You can destroy Rex's Solidariy by using this trap card. Can be activated during Rex's turn.
Wild Tornado
Wild Tornado
Can be used to destroy Solidarity, but only set one of these so you do not clog your spell/trap zone since it cannot target Jurassic World.


My ElementsUnite Deck.
Needs only 2x Union and no Cards from CrimsonKingdom.
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?
