Super powerful burn effect + best mill effect in the game in-element with one of the best stall cards in the game i.e. Phase Shield? No thank you.
Need clarification, does a player who has 7 cards in the beginning of the turn (draws only 1 card) take the 10 damage? Although this would make it less deadly, it'd also open up a potentially imbalanced combo with the in-element card Silence.
