Lifelink, haste

Flying When this creature enters, if it was cast, each player exiles all but the bottom six cards of their library face down. At the beginning of your upkeep, draw a card.

Add {B}{B}{B}. Threshold — Add {B}{B}{B}{B}{B} instead if seven or more cards are in your graveyard.

Destroy target creature with total power and toughness 5 or less.

This land enters tapped unless you control a Swamp. {T}: Add {B}. {1}{B}{B}, {T}: Draw a card, then you lose life equal to the number of cards in your hand.

Each player mills ten cards. For each player, choose a creature or planeswalker card in that player's graveyard. Put those cards onto the battlefield under your control. Then each creature you control becomes a Phyrexian in addition to its other types.

Search your library for a card, put that card into your hand, then shuffle.
