MTG Ayara, First of Locthwain Deckby Olivier

Whenever Ayara or another black creature you control enters, each opponent loses 1 life and you gain 1 life. {T}, Sacrifice another black creature: Draw a card.

Whenever one or more nontoken creatures you control die, investigate. This ability triggers only once each turn. (Create a Clue token. It's an artifact with "{2}, Sacrifice this token: Draw a card.")

At the beginning of your end step, if you control no creatures with decayed, create a 2/2 black Zombie creature token with decayed. (It can't block. When it attacks, sacrifice it at end of combat.)

{T}: Target creature card in your graveyard perpetually becomes an artifact. You may cast that card this turn. (It loses all other card types.)

Equipped creature gets +1/+1 and has trample and lifelink. {1}: Permanents your opponents control lose hexproof and indestructible until end of turn. Equip {2}

{1}{B}, Pay 2 life: Return target creature card from your graveyard to your hand.

Add {B}{B}{B}.

You may pay {1}{B} rather than pay this spell's mana cost. If the {1}{B} cost was paid, an opponent draws a card. Exile target creature or planeswalker.

Destroy target creature or enchantment an opponent controls. You lose life equal to that permanent's mana value.

Choose one or more — • Each player discards two cards. • Each player loses 4 life. • Each player sacrifices two creatures of their choice.

Choose one — • Destroy all creatures. • Destroy all planeswalkers. Then return a creature or planeswalker card with mana value X or less from your graveyard to the battlefield, where X is the amount of {S} spent to cast this spell. ({S} is mana from a snow source.)

({T}: Add {B}.)
