Mercadian Block

Mercadian Block (Visual)

Everything is from Mercadian block.
There is no 5-color identity Legendary Creature from Mercadian block, so I punted and use Harvest Mage (since it references "any color" at least).
If someone ever were to balk at it (no one ever does), I would go off-theme and use Sliver Queen.
