For those reptilian styled players who enjoy games ending by turn 5 or less and want each game to be the equivalent of pulling a slot machine lever or tic-tac-toe.
Turbo mode would double mana gain each turn, lower maximum life to 15 and lower maximum deck size to 12.
This mode would take pressure off of the power creep the cards so dramatically each expansion, blurring the lines of each class and thus allowing for more interactive and cerebral games with more definitive class architypes.
