The Frestad

Permanents you control gain "tap target
Assembly-worker creature you control,
pay 2, and untap this permanent: add a time
counter on target card you own in exile.
Nonland permanents you control don't untap
during your untap step.
Whenever you cast a spell from your hand,
exile it instead and add time counters to it equal
to half of the amount of mana you spent to cast
it, rounded down.
