Ichifive, The Jagged Master

Oddity
As long as it's your turn, you may cast creature
spells with odd converted mana costs from your
hand without paying their mana cost. If you do,
they gain "Discard a creature card with an even converted mana cost: Counter this spell. Any
player may activate this ability."
"The Jagged Path demands a defiance of convention.
What better convention to defy than reality? "
