(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.)

,

Until your next turn, creatures you control gain "

: Add one mana of any color."

Put a +1/+1 counter on each creature you control. Those creatures gain
vigilance (Attacking doesn't cause this creature to tap.),
trample (This creature can deal excess combat damage to the player or planeswalker it's attacking.), and
indestructible (Effects that say "destroy" don't destroy that permanent. An indestructible creature can't be destroyed by damage.) until end of turn.
