Syler, Basking in Riches

Hexproof, deathtouch
Whenever a creature dealt damage by Syler is sent to a graveyard, return it to the battlefield under your control except it can't attack or block.
At the beginning of your end step, create X colorless artifact tokens named Gold for each other creature you control that you don't own. They have "Sacrifice this artifact: Add one mana of any color to your mana pool."
