Necrotic Sliver

4, T: Search your library for a Rebel permanent card with mana value 3 or less, put it onto the battlefield, then shuffle.

This creature can't be blocked except by artifact creatures and/or white creatures.

Flash; convoke (Your creatures can help cast this spell. Each creature you tap while casting this spell pays for 1 or one mana of that creature's color.) Flying When this creature enters, prevent the next 5 damage that would be dealt this turn to any number of targets, divided as you choose.

Split second (As long as this spell is on the stack, players can't cast spells or activate abilities that aren't mana abilities.) You can't lose the game this turn and your opponents can't win the game this turn. Until end of turn, damage that would reduce your life total to less than 1 reduces it to 1 instead.

Flash Flying If an opponent would search a library, that player searches the top four cards of that library instead.

Flying Vanishing 3 (This creature enters with three time counters on it. At the beginning of your upkeep, remove a time counter from it. When the last is removed, sacrifice it.) When this creature enters or leaves the battlefield, you gain 2 life.

Flanking (Whenever a creature without flanking blocks this creature, the blocking creature gets -1/-1 until end of turn.)

Benalish Commander's power and toughness are each equal to the number of Soldiers you control. Suspend X—XWW. X can't be 0. Whenever a time counter is removed from this card while it's exiled, create a 1/1 white Soldier creature token.
