Shub Niggurath

{x} must be equal to the amount of Cards in your hand when you cast Shub Niggurath.
At the Begining of your Draw phase create X 1/5 Spawn tokens where X is equal the Cards in your Hand + 3.
At the Beginning of your opponents draw phase sacrifice X Spawn tokens where X is the amount of Cards in your opponents hand - 3. Shub Niggurath gets +1/+1 counters equal to the tokens sacrificed this way.
