Firebrand Genius

Renown 1 (When this creature deals combat damage to a player, if it isn't renowned, put a +1/+1 counter
on it and it becomes renowned.)
When Firebrand Genius becomes renowned, you may cast an instant or sorcery card with converted mana cost 5 or less from your hand without paying its mana cost.
"There are some foes that no amount of honourable bladework will overcome. That's where I come in."
