Solstice, Stopper of the Sun

Deathtouch, hexproof
At the beginning of your upkeep, if it's night,
put a time counter on Solstice, Stopper of the
Sun and create a 2/1 black Elemental creature
token with flying.
When the fifth time counter is placed on Solstice, create ten Blood tokens. Until the next end step, activated abilities of artifacts you control cost {1} less to cast.
