Hypothesizzle
Instant
Draw two cards. Then you may discard a nonland card. When you do, Hypothesizzle deals 4 damage to target creature.

• #GRN-178Rulings
You don't choose a target creature at the time you cast Hypothesizzle. Rather, a second "reflexive" ability triggers when you discard a nonland card. You choose a target for that ability as it goes on the stack. Each player may respond to this triggered ability as normal. Notably, the triggered ability isn't a crime, but the reflexive triggered ability potentially is.
