I am a player of Magic: The Gathering Arena, and I would like to raise a concern regarding the card "Mana Drain" in the Brawl format. I believe this card is currently too powerful, negatively impacting the gameplay experience.
"Mana Drain" counters a target spell, and during the next phase, it adds {C} to the player's mana pool equal to the spell's converted mana cost. This effect gives the player a significant mana advantage, which can be overwhelming, especially in the more diverse and creative decks typical of Brawl. This often results in an unfair advantage for the player using "Mana Drain," as it not only denies an opponent a key spell but also grants a large mana boost, leading to one-sided and unbalanced matches.
Given this, I would like to suggest that "Mana Drain" be banned from Brawl mode to improve the balance and fairness of the format. I believe this change would help make the gameplay more enjoyable and fair for all players.
