Debtors' Knell

Whenever a Kraken, Leviathan, Octopus, or Serpent you control deals combat damage to a player, create a 9/9 blue Kraken creature token.

You may have this artifact enter as a copy of any artifact on the battlefield.

Choose one — • Draw cards equal to the greatest power among non-Human creatures you control. • Non-Human creatures you control get +3/+3 until end of turn.

Destroy target creature. It can't be regenerated. That creature's controller creates a 3/3 green Frog Lizard creature token.

Flying 1B, T: Rather than pay the mana cost of the next spell you cast this turn, you may pay life equal to that spell's mana value.

Return all artifact cards from your graveyard to the battlefield. They gain haste until end of turn.

Whenever you cast an artifact spell, you may pay 2. If you do, create a 0/0 colorless Construct artifact creature token with "This token gets +1/+1 for each artifact you control."

B, Pay 2 life: Draw a card.
