MTG Salvation

The caudron is bad. At best is 5 mana (and pay 2 life) to reanimate a creature (IF you have 5 creatures in the grave).
In standard we already have a 5 mana reanimator card that gives the creature haste.

If you want a repeatable reanimator card for EDH you can already use Whip of Erebos, Recurring Nightmare ,Dread Return, Mimic Vat etc.

Also the wheel of sun and moon effect is pretty awkward.
