Magic The Gathering Cards of types 'Snow' and 'Elk'

This creature gets +2/+2 as long as you had another creature enter the battlefield under your control this turn.

As an additional cost to cast this spell, you may open a sealed Magic booster pack and put the cards on the bottom of your booster pile in a random order. Spells you cast have booster cascade. (It's like cascade, but use your booster pile rather than your library.)
