When Runeforge Champion enters, you may search your library and/or graveyard for a Rune card, reveal it, and put it into your hand. If you search your library this way, shuffle.
You may pay rather than pay the mana cost for Rune spells you cast.
Runeforge Champion's last ability provides an alternative cost to cast Rune spells. You can't combine this with other alternative costs that may apply. In the unusual case that a Rune spell has additional costs, you can pay those in addition to the {1}. If those additional costs are mandatory, you must pay them in order to cast the spell.
