Trample, haste
Whenever Jaws deals combat damage to a player, create that many Blood tokens. (They're artifacts with "{1}, {T}, Discard a card, Sacrifice this token: Draw a card.")
Whenever a noncreature artifact is sacrificed or destroyed, Jaws deals 1 damage to each opponent.
Roll two d12 and choose one result. Reckless Endeavor deals damage equal to that result to each creature. Then create a number of Treasure tokens equal to the other result.
{R}: You may put a creature card from your hand onto the battlefield. That creature gains haste. Sacrifice the creature at the beginning of the next end step.
