Target player reveals their hand. You and that player secretly choose a nonland card from it. Then those cards are revealed. That player discards the chosen cards.

Whenever one or more cards leave your graveyard for the first time each turn, create a 3/2 green Crocodile creature token with trample.

Choose target opponent. Scry 3, then reveal the top card of your library. The chosen player discards an amount of cards equal to that card's mana value. (To scry 3, look at the top three cards of your library, then put any number of them on the bottom of your library and the rest on top in any order.)

Audition for black. (Create a 1/1 Construct Actor creature token, a Cleric Role giving 2/2 and lifelink, or a Warlock Role giving 2/1 and flying. Roles replace older ones.)
Until end of turn, if a creature you don't control would die, instead exile it and that creature's controller loses 2 life.

Reconstruct {4}{B}{B}{B} (You may cast this from your graveyard for its reconstruct cost reduced by the mana value of a permanent you sacrifice as you cast it this way. Then exile this.)
Destroy all creatures. If The Afterlife Takes Its Due was reconstructed, create an X/X black Zombie Horror creature token, where X is the number of creature cards that have been put into graveyards this turn.

Target player discards two cards.
Ferocious — That player discards two cards at random instead if you control a creature with power 4 or greater.

I — Return target creature card with mana value 2 or less from your graveyard to the battlefield.
II — Each opponent loses 2 life and you gain 2 life.
III — Return target creature card with mana value 2 or less from your graveyard to the battlefield.
