Fel, Thaumaturge Genius

When Fel enters the battlefield, create a
Thaumaturge token with base power and
toughness 0/6
The next time a player casts a spell, if you
control a Thaumaturge token, sacrifice it
and then choose one at random:
- That player loses 5 life and mills 2,
- Counter that spell and surveil 2,
- You draw 3 cards and lose 3 life
