When El-Hadid enters battle with an opposing champion the opponent choose up to 4 cards from his hand and lay them on the table face up for all to see. Only these cards may be used by the opponent in the battle against El-Hadid, the rest of the opponent's hand is set off to the side and may not be used until the battle with El-Hadid is resolved. Any cards played with El-Hadid that effect the opponent's hand will effect only the minihand, such as the Athasian Sloth (230/4th) or Ninjas (239/4th). Any cards that affect the hand after battle is over, like The Starving Artist (439/3rd), will work as normal.
El-Hadid is a potent Birthright champion as well as thief and works well in both types of decks. His low level will usually allow the player to lay the first card in battle. This makes El-Hadid especially powerful when combine with allies that discard cards from your opponent's minihand. El-Hadid can even be found in a small number of standard tournament decks and has been found to be very effective for players that enjoy attacking and use a combination of thief skills and blood abilities.
