This skill can be used in farming decks, it is a good option to include in a farm deck for Standard Duelists since it is easier to get the score “LP on the brink”, and Standard Duelists are not as predictable as Legendary Duelists. It is also used in burst decks with spell cards to deal effect damage to your opponent. These decks usually make you lose cards fast so this skill can help you fill your hand again.
Can be used in your Main Phase, starting from the fifth turn. Upon activation, reduces your LP to 100 and discards 2 cards from your hand. You roll a die and draw that number of cards. This skill can only be used once per Duel.
This skill is not popular in ranked matches currently since it would be useful only in the late game as a last resource to save your duel if you draw well. Compared to other skills, it is not so reliable because you need to decrease your LP to almost 0 and also discard 2 cards. It fits better in burst decks with defensive monsters, but they are also not reliable.
Try auto dueling the legendary duelists in the world, that's how I got the skill from lvl 30 Yugi. It isn't much but it's time efficient. You'll be pleasantly surprised, that's how I got all the skills for the Paradox Bros.
