Infernal Sovereign

Give up your draw step forever, and every subsequent action you take hands it back with interest. That inversion is the engine: where most black card advantage taxes life for a discrete, one-time effect, this one converts the mechanical act of playing lands and casting spells into a Phyrexian Arena that scales with your own tempo. The trigger is precise, and the precision is where greedy pilots leak value: it wants a land actually played or a spell cast, so a cracked fetchland (an activated ability putting a land onto the battlefield) does nothing here, and neither does a token copy or a permanent flickered in. Hardcast a rock, drop a land for turn, chain two spells, and you have netted four cards for four life. The life runs alongside the draw, so an unchecked engine eventually kills its own pilot; the clock points both directions at once. The design leans on how invisible the draw step is: you rarely think about it until something takes it away, and here the surrender is the price of admission, not a downside to minimize. The 6/6 flying, trample body is not decoration; it closes games while the engine burns, which matters when the pilot is racing their own life total. Storm-style turns and life-as-resource shells find the ceiling absurd, but the card punishes stillness: play nothing, and you draw nothing at all, having traded your normal draw for the privilege of doing so.
