Espa Roba cannot change your monsters to attack position or raise his attack above 2800 so your Labyrinth Wall/Dark Necrofear will be mostly safe throughout the Duel.
The only way Espa Roba can destroy Labyrinth Wall/Dark Necrofear is by using Tribute to the Doomed, which he has only 1 copy of.
Use Sphere Kuriboh and/or Kuriboh to block attacks and stall turn.
Doomdog Octhros and Dark Mimic to catch attacks without losing card advantage and thin your deck quicker.
Remove from play fiend type monsters in your graveyard to summon Dark Necrofear. Only special summon her in defense position.
It is best to keep at least 2 Dark Necrofear and or Labyrinth Builder on the field.
On the final turn, put your Dark Necrofears and or Labyrinth Builder in attack position then use Shield and Sword. Summon Gravekeeper's Vassal and use Secret Pass to the Treasures and 2 Union Attack on him. Use Anti-Magic Arrows then direct attack for 9999+ damage.
This deck is good because it is very efficient at getting cards from your graveyard and your deck. Letting you get the cards you need quickly while maintaining card advantage.
Espa Roba's Tribute to the Doomed can't do much against you since you can easily summon another big monsters with this deck. Additionally, you have the option to remove Machine Angel Ritual from your graveyard so that your monster is not destroyed.
Use Idaten as a ritual material to increase the attack and defense of all your ritual monsters on the field by 1000 points.
Always use Dakini to retrieve Idaten and then a ritual spell if possible.
On the final turn, Summon Gravekeeper's Vassal and use Secret Pass to the Treasures and 2 Union Attack on him. Use Anti-Magic Arrows then direct attack for 9999+ damage.
A Trick Up the Sleeve Your starting hand will include 1 Lvl 7or higher DARK spellcaster-type monster, randomly selected from your deck. This skill will not activate if your DECK does not include 1 Lvl 7 DARK spellcaster-type monsters.
I used six sams to farm it. Shien can negate spells and traps throughout the duel, 2 shien with union attack is enough to get vassal over 10k damage. fuma offers protection from tribute to the doom in a pinch econ can deal with reflect bounder. can even thin your deck to speed things up with united. Happy I found an answer that didnt involve anti magic arrows, as i dont have it yet.
Maybe it's just my bad luck this time but this is the first event where UR/SR drops are so fricking bad. I mean there's examples where I don't get any UR/SR for 4,5 duels in a row (with 7-8k farms) and when I get something it's usually an old card I already have like pulse mines. So frustrating
What extension?! The event is originally planned to end on February 23 or 22 (depending on your timezone)
I discovered that you can use the new red eyes fusion monster in the Paladin deck. I used it and it not only boost paladin but can make the combined atk much higher than Dark Flare Knight since it can get to 3200atk with a space free for the Vassal/Treasures/UA combo.
Also, with Red-Eyes Slash Dragon if you do attack to use it's ability and Roba uses Pulse Mines it would still equip Buster regardless. Plus it increases the ATK boost from one UA to 6600 compared to only 5100 which is an 1500 difference. Even so, it even helps on negating Cyber Raider's effect when you're against his lv30 deck as well.
