One of the most useful farming skills for starters, allowing you to draw Mythical Beast Cerberus in farming handful of duelists at the gate. This skill is easily obtained by one of the main characters, Yami Yugi by just leveling up and to receive high duel assessment.
Can be used each time your Life Points decrase by 1800. In the Draw Phase, instead of doing a normal draw, draw a random Spellcaster-Type monster.
This skill has proven worthy than any other exclusive skills for starters. Farming made easy by this skill. However, using it on PVP is not recommended because it gives you "random" spellcaster. Most spellcaster decks are using a more viable skill like Power of Dark.
