- 1 February 2014If you control more than one Ragemonger, the cost reduction is cumulative.
- 1 February 2014If a spell has hybrid mana symbols in its mana cost, you choose which half you will be paying before determining the total cost. If you choose to pay such a cost with {B} or {R}, Ragemonger can reduce that part of the cost.
- 1 February 2014You apply cost reduction effects after other cost modifiers, so Ragemonger can reduce additional costs or alternative costs of Minotaur spells if they include {B} and/or {R}.
