This strat will give you consistent sub-4:00 A-TECs on Nitemare if your deck is very good. Some 100% runs will not be good enough to try this initially, although you can modify it by doing 5 fusions and 5 equips instead of 1 fusion and 10 equips. 1 fusion 33 cards used (7 remaining) 1 face-down play 2 effective attacks 10 equips 1 pure magic 3 traps 9 turns <7000 LP Video demonstration: https://www.youtube.com/watch?v=8jmcasYaS5k This A-TEC has one major difference from the most commonly used A-TECs: It ends the duel with 7 cards remaining rather than 3. This saves a turn if all goes well. A typical duel goes something like this: Turn 0 (35 cards left): Set trap Turn 1 (34): Set magic (take damage) Turn 2 (33): Toss 4, play something big, 1st effective attack Turn 3 (29): Toss 5, play something big, 2nd effective attack Turn 4 (24): Set trap Turn 5 (23): Set trap Turn 6 (22): Toss 5, play something weak (or MBD in Defense), activate 2nd and 3rd traps Turn 7 (17): Toss 5, play something big Turn 8 (12): Toss 5, play something big Turn 9 (7): Play anything, activate face-down magic, attack 1-2 times to win If you don't draw your magic on turn 1, you will have to find another way to take damage. For this reason, it is recommended to have some monsters with <2000 Attack in your deck, such as thunders or Meteor Dragon. The hardest part about this A-TEC is using 10 equips in only 33 cards. If you have only 10 equips in your deck, you likely won't draw them all in time. Also, some common equips, such as Sword of Dark Destruction, only work on a few monsters, so you may have to toss them to win the duel in 9 turns. To make this strat consistent, you need 13-14 equips, and at least 10 of them should be good equips like Dark Energy that work on most of your monsters. The aforementioned 5 fusion, 5 equip route is also viable, especially if you have multiple Dragon Zombies. However, you'll need to take out some equips and/or big monsters to make room for the fusions, which will make Nitemare's biggest monsters a little tougher to take down. ----- Optimal deck (added 12/4/22) (assumes no Zoa or THTD; both help if you have them) *18 MONSTERS* 3 Curse of Dragon 3 Meteor B.
