Flying {S}{S}: This creature gains shroud until end of turn. ({S} can be paid with one mana from a snow source. A creature with shroud can't be the target of spells or abilities.)

{S}, {T}: Look at the top card of your library. If it's a snow card, you may reveal it and put it into your hand. ({S} can be paid with one mana from a snow source.)

Reveal the top six cards of your library. You may put any number of snow permanent cards from among them into your hand. Put the rest into your graveyard.

Flash Flying When this creature enters, draw a card. This creature has deathtouch as long as you control at least three other snow permanents.

You may look at the top card of your library any time. You may play snow lands and cast snow spells from the top of your library. Whenever another snow permanent you control enters, you may pay {G}, {W}, or {U}. If you do, put a +1/+1 counter on Isu.

({T}: Add {U} or {B}.) This land enters tapped.

{T}: Add {C}. {4}{S}, {T}, Sacrifice this land: It deals 4 damage to target creature. ({S} can be paid with one mana from a snow source.)

This land enters tapped. As this land enters, choose a color. {T}: Add one mana of the chosen color.

({T}: Add {G}.)

{T}: Untap another target snow permanent.

Trample Abominable Treefolk's power and toughness are each equal to the number of snow permanents you control. When this creature enters, tap target creature an opponent controls. That creature doesn't untap during its controller's next untap step.

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.)
