Myr Battlesphere

The seven-mana payoff that taught a generation of artifact players to count their Myr. The body alone is a fair trade: a 4/7 that arrives with four 1/1 tokens, so it lands as nineteen points of stats spread across five bodies and clogs a board immediately. But the attack trigger is the engine, and it scales off something the deck building has usually already supplied. Tapping X Myr to pump the Battlesphere AND fling X damage straight at the player or planeswalker it's attacking turns a wide Myr board into a single overwhelming swing, often killing through a wall of blockers the tokens could never push past on their own. It converts width into reach, rewarding the most natural thing a Myr deck does anyway: flood the board with small artifact creatures. The design is honest about its ceiling. The tokens it makes are themselves Myr, so the card can later fuel its own ability, but the explosive turns come from the dorks and one-drops already in play, not from the Battlesphere in isolation. It is a finisher that asks you to have done the work upfront, a capstone for tribal artifact strategies that want a top-end threat doubling as a haymaker. Where Myr were already a clan worth assembling for mana, this is the card that gave them a reason to attack.
