Visionary Mentor

Whenever you cast a creature spell, you may pay
{g/u}{g/u}{g/u}. Your creatures gain hexproof
until end of turn.
Whenever you cast a non-creature spell, you may
pay {g/u}{g/u}{g/u}. Tap target creature and untap
target creature.
Remember, visualise your goals and there will be
nothing to fear.
