How much mana does a person have to put in their deck to not draw only mana but also draw mana regular enough to play a competitive game!!! I’m sick and tired of losing game over game because all of the sudden I can’t draw any mana BUT if I add any more mana to my deck (making up half the deck), then all I draw is mana. This is a basic mechanic problem, why is this still going on! I constantly have to stop playing for periods and then come back to see if the gameplay has been fixed but nope. Thanks Wizards of the coast, I shan’t be buying your products for terribly inconsistent gameplay.
