Description: can be used when your lp drop at 2000 or lower, instead doing normal draw, you can draw whatever broken cards outside your deck, you can use this skill until you completely screw your opponent
I'm way past that point, so I don't remember the details. First, does it mention which Level you have to beat? If not, you can probably try to complete this mission with the Lv10 Yami Yugi. You should fill your deck with 50% powerful 4* monsters and 50% really weak monsters (preferably at 0 ATK).
Summon a strong monster, and the Lv10 Yugi shouldn't be able to beat you. After that, you can begin summoning your super weak monsters to take damage intentionally. Alternatively, you can just use cards that cost you LP. The key is to reduce your LP at your own pace.
