When High Marshal Arguel dies, conjure a card named Arguel's Blood Fast onto the battlefield and you may transform it. If you control an enchantment named Arguel's Blood Fast and a land named Temple of Aclazotz, instead create two 4/3 white and black Vampire Demon creature tokens with flying.
Whenever a player draws their second card each turn, any of their opponents may say "DRAW!". The first opponent to do so clashes with that player. The player that wins the clash creates two 1/1 black Assassin creature tokens. (Each clashing player reveals the top card of their library, then puts that card on the top or bottom. A player wins if their card had a higher mana value.) Whenever Chaos ensues, draw a card.
Whenever High Perfect Morcant or another Elf you control enters, each opponent blights 1. Tap three untapped Elves you control: Proliferate. Activate only as a sorcery.
If one or more +1/+1 counters would be put on a creature you control, that many plus one +1/+1 counters are put on it instead. At the beginning of your end step, draw a card if you control a creature with the greatest power among creatures on the battlefield.
Whenever you planeswalk here, starting with you, each player chooses up to 5 ♦ worth of modes and may choose the same mode more than once. (Then Planeswalk away from this phenomenon.) ♦ — Create a Treasure Token. ♦ ♦ — Draw a card. ♦ ♦ ♦ — Create a 3/2 colorless Shapeshifter creature token with Changeling.
Flying Whenever this creature attacks, you may sacrifice another creature. If you do, put a +1/+1 counter on this creature. Whenever another nontoken creature dies, draw a card.
"You've been a marvelous servant. Consider this your final assignment."
With the bloodchiefs annihilated in the fight between the free and enthralled, the swamps around Malakir are full of dangerous, young vampires eager to make their marks.
Vigilance When this creature enters, for each opponent, choose a creature with the greatest power among creatures that player controls. Destroy those creatures.
Once the felidar has marked you as prey, there's no point in running.
You may have this creature enter as a copy of any creature on the battlefield, except it enters with an additional +1/+1 counter on it and it's the colors of your choice in addition to its other colors.
