Pyromancy 101

Pyromancy 101 is exiled taught to the chosen creature as part of that spell’s resolution, just after its other effects. It goes directly from the stack to exile. It never goes to the graveyard.

The copy of Pyromancy 101 created by the granted activated ability can’t be taught after it resolves.

For many playtest cards, you’ll need to make a generous assumption that basic game rules would be updated to allow them to work. The Mystery Booster 2 Playtest Card Notes section (reproduced here in individual Gatherer rulings) provides guidance for fitting these cards into the existing rules structure.
