Glacierwood Siege (TDM 189)

Enchantment • Mana cost: {1}{G}{U} • Tarkir: Dragonstorm • Rare

As this enchantment enters, choose Temur or Sultai.
• Temur — Whenever you cast an instant or sorcery spell, target player mills four cards.
• Sultai — You may play lands from your graveyard.

The Sultai approach was silent. The Temur response was deafening.
