Monument of The 3 Pillars

You may exile five instant and sorcery cards
from your graveyard rather than pay this spell's
mana cost.
Tap all the creatures your control: Draw two
cards. Until end of turn, you may cast instant
and sorcery cards from your graveyard without
paying their mana cost. If you do, exile them
instead of putting them into your graveyard.
Activate this ability only if you didn't attack
this turn.
