Everstorm, Odium's Storm

At the beginning of each upkeep, every creature
takes X damage. If a player controls Urithiru or
an Odium card, their creatures are immune to
this effect.
When a Fused creature is put in the graveyard,
immediately return it to your hand.
All Fused Creatures gain a +1/+1 counter and have
haste.
"I have seen the end, and have heard it named.
The Night of Sorrows, the True Desolation. The
Everstorm."
