Ice Age Block

Ice Age Block (Visual)

Everything is from Ice Age block.
There is no 5-color identity Legendary Creature from Ice Age block, so I use one of only two 5-color identity cards available: the rather terrible Naked Singularity.
In practice, I never cast the general anyway, as it's a douchey move. If someone ever were to balk at it (no one ever does), I would go off-theme and use Sliver Queen.
