You may reveal this card from your opening hand. If you do, at the beginning of your first upkeep, look at the top four cards of your library. You may put one of those cards back on top of your library. Exile the rest. When you cast this spell, exile target permanent that's one or more colors.

Choose two — • Target player creates X 0/1 colorless Eldrazi Spawn creature tokens with "Sacrifice this creature: Add {C}." • Target player scries X, then draws a card. • Exile target creature with mana value X or less. • Exile up to X target cards from graveyards.

+2: Ugin deals 3 damage to any target. −X: Exile each permanent with mana value X or less that's one or more colors. −10: You gain 7 life, draw seven cards, then put up to seven permanent cards from your hand onto the battlefield.

{T}: Add {C}. {T}: Add {C}{C}. Spend this mana only to cast colorless Eldrazi spells or activate abilities of colorless Eldrazi.

({T}: Add {G}.)

Imprint — When this land enters, you may exile a colorless card with mana value 7 or greater from your hand. {T}: Add {C}. If a card is exiled with this land, add {C}{C} instead. {T}: Return the exiled card to its owner's hand.

{T}: Add {C}. If you control an Urza's Power-Plant and an Urza's Tower, add {C}{C} instead.

{T}: Add {C}. If you control an Urza's Mine and an Urza's Tower, add {C}{C} instead.

This artifact enters with X charge counters on it. Whenever a player casts a spell with mana value equal to the number of charge counters on this artifact, counter that spell.

{2}, {T}, Sacrifice this artifact: Search your library for a land card, reveal it, put it into your hand, then shuffle.

Devoid (This card has no color.) Kicker {1}{C} (You may pay an additional {1}{C} as you cast this spell.) When you cast this spell, search your library for a land card, put it onto the battlefield, then shuffle. When you cast this spell, if it was kicked, exile target land.
