Bael-Grimnir, Runefather

Vigilance, battle cry
When you cast Bael-Grimnir, for each mana
from a Treasure spent on {r/w} to cast it, search
your library for a basic mountain card, put it
onto the battlefield tapped, then shuffle.
Magmadroth Blood - Whenever Bael-Grimnir is
dealt damage, it deals that much damage to any
target.
