Joseph, Arcane Master

Whenever you cast a spell that only targets Ben, Warlock Master, you may create a copy of
that spell for each other creature you control and
have them target those creatures.
At the end of each turn, for each instant or
sorcery you have cast that turn, you may draw a
card, gain 3 life, deal 3 damage to any target or
make a 1/3 white warlock creature token with
double strike.
