Zeyshaan, Shadow Titan

Companion — Your deck contains at least 4
copies of each nonland card. ( If this card is
your chosen companion, you may cast it once
from outside the game. )
Whenever an opponent casts a spell, if no
creatures enter the battlefield before that
spell resolves, you may gain 2 life and draw a
card. If a creature does enter the battlefield
before that spell resolves, target opponent
discards 2 cards and loses 5 life.
