(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.)I — You may exchange control of two target creatures.II — You may exchange control of two target nonbasic, noncreature permanents that share a card type.III — Target player loses 3 life and you gain 3 life.
Choose target creature you control and target creature you don't control. If you control three or more snow permanents, the creature you control gets +1/+0 and gains indestructible until end of turn. Then those creatures fight each other. (Each deals damage equal to its power to the other.)
Enchant permanentWhen Rune of Mortality enters, draw a card.As long as enchanted permanent is a creature, it has deathtouch.As long as enchanted permanent is an Equipment, it has "Equipped creature has deathtouch."
If a nontoken creature an opponent controls would die, exile that card with an ice counter on it instead.You may cast spells from among cards in exile your opponents own with ice counters on them, and you may spend mana from snow sources as though it were mana of any color to cast those spells.
: Target snow land you control becomes a 4/4 Elemental creature with hexproof and haste until end of turn. It's still a land. (A creature with hexproof can't be the target of spells or abilities your opponents control.)
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.
