Dire Miralis, Pyre-enhancer

Companion - Your starting deck contains only cards
with odd converted mana costs and land cards. (If
this card is your chosen companion, you may cast it
once from outside the game.)
If a source you control with an odd converted mana
cost would deal damage to a permanent or player, it
deals double that damage to that permanent or
player instead.
