Machine de guerre de Mishra 266/306

Banding (Any number of creatures with banding, up to one without banding, can attack in a band. Bands are blocked as a group. If a creature with banding you control blocks or is blocked by a creature, you divide rather than assign its combat damage among the creatures blocking or blocked by it.) At the beginning of your upkeep, Mishra's War Machine deals 3 damage to you unless you discard a card. If Mishra's War Machine deals damage to you this way, engage it.
