During either player's Battle Phase, if you control a "Silent Magician" monster and you have more cards in your hand than your opponent: Each player draws until they have 6 cards in their hand. This card's activation and effect cannot be negated. You can banish this card from your Graveyard; add 1 "Silent Magician" monster from your Deck to your hand.
The effect of this card to draw until each player has 6 cards in their hand, greatly increases Silent Magician’s ATK stats. It can also be banished from your Graveyard to search for any “Silent Magician” monster from your Deck to your Hand.
These are the examples of Spell and Trap cards that require a discard as a cost to activate, and you can opt to discard Silent Burning to activate their effects, and banish Silent Burning to retrieve 1 “Silent Magician” monster from your Deck to your Hand
Unfortunately, Konami has the dumbest idea of ruling that this card let players draw the cards AT ONCE. As in, even if the player draw 5 cards through this card, it's still treated as a single drawing action, thus Silent Magician LV4 only gains 1 counter, not 5......
