First strike
When Combustible Gearhulk enters the battlefield, target opponent may have you draw three cards. If the player doesn't, put the top three cards of your library into your graveyard, then Combustible Gearhulk deals damage to that player equal to the total converted mana cost of those cards.
At the beginning of your upkeep, put target creature card from a graveyard onto the battlefield under your control.
Whenever a creature you control attacks, it gets +1/+0 until end of turn for each other attacking creature that shares a creature type with it.
Whenever a creature you control dies, each other player sacrifices a creature.
