Exile the top eight cards of your library. You may put a land card from among them onto the battlefield. Until end of turn, for each nonland card type, you may cast a spell of that type from among the exiled cards without paying its mana cost.

Roll two d8 and choose one result. Draw cards equal to that result. Then you may cast an instant or sorcery spell with mana value less than or equal to the other result from your hand without paying its mana cost.

As an additional cost to cast this spell, discard a card. Draw two cards and create two Treasure tokens. (They're artifacts with "{T}, Sacrifice this token: Add one mana of any color.")

Draw two cards, then discard two cards.

Draw two cards. Then discard a card unless you attacked this turn.

As this land enters, you may reveal an Elemental card from your hand. If you don't, this land enters tapped. {T}: Add {R}. {R}, {T}: Target creature gains haste until end of turn.

As this land enters, you may reveal an Island or Mountain card from your hand. If you don't, this land enters tapped. {T}: Add {U} or {R}.

({T}: Add {U}.) This land enters tapped unless you control three or more other Islands. When this land enters untapped, you may put target instant or sorcery card from your graveyard on top of your library.

{T}: Add {C}. {T}: Add {U} or {R}. This land deals 1 damage to you.

Hideaway 4 (When this land enters, look at the top four cards of your library, exile one face down, then put the rest on the bottom in a random order.)

Counter target spell that targets a permanent you control.

When this enchantment enters, create two Treasure tokens. The first spell you cast each turn that mana from a Treasure was spent to cast has cascade.

Put the exiled cards on the bottom in a random order.)
