Tome of Horrors

When you cast a creature spell, if it doesn't have the same name as a creature on the battlefield or in your graveyard, create an
X/X green horror token, where X is its converted mana cost. The token enters the battlefield with a number of counters
chosen from deathtouch, first strike, flying, haste, hexproof, lifelink, menace, trample or +1/+1 equal to half X rounded down.
