Muhammad Avdol

Muhammad Avdol is a Rare Stand User-type Unit Card with 1 attack and 3 health. His mana cost is 4 and he has the modifier Deathrattle which steals one card from your opponent's Deck and moves it to your Hand.

Strategy
While Avdol may seem like a weak unit for 4 mana, his allure is not in his stats, but his modifier, Deathrattle.

One of the most common deck types is the "Rush"/"Swarm" type, involving getting as many units on to the field as fast as possible and focusing the opposing Champion. One of the major issues with these types of decks is Deck Drain, or burning through your deck without adequate returns.

The other most common type of deck is Mid-Range, using mid to high cost units (5 to 10 mana) to get better returns per unit. Rush decks drain cards much faster than Mid-Range decks due to running cards like Lisa Lisa, Baron Zepppeli, Harvest (Collector Mode), and Straizo.

This is what causes Deck Drain. For example, if you run Bites the Dust, it possible to screw over some Rush decks by playing the card when the opponent's field is very full, making their hand up to or greater than the 10 card limit when the units are sent back, forcing the game to make them discard their next turn's draw.

This is where Avdol comes in, his ability takes a card from the opponent's deck, which aids you twofold, giving you a free card to keep you deck lasting longer, while draining the opponent's deck even faster. If both sides are using Rush decks, or even if just one is, the game goes from strategy to something more of a candle burning contest. Once the wick is lit, who's deck will have more "burn time", your's or the opponent's? Avdol helps to make sure the answer will always be your opponent.
