Whenever an opponent casts a spell, you may draw a card unless that player pays {1}.

Each player shuffles their hand and graveyard into their library, then draws seven cards. (Then put Timetwister into its owner's graveyard.)

({T}: Add {B} or {R}.)

({T}: Add {B} or {G}.)

{T}: Draw two cards, then discard three cards.

As this land enters, choose a creature type. {T}: Add {C}. {T}: Add one mana of any color. Spend this mana only to cast a creature spell of the chosen type, and that spell can't be countered.

{T}: Add {G} for each creature you control.

{T}: Add {C}{C}{C}. Spend this mana only to cast artifact spells.

({T}: Add {R} or {W}.)

({T}: Add {G} or {W}.)

({T}: Add {W} or {B}.)

({T}: Add {R} or {G}.)

All creatures have "At the beginning of your upkeep, destroy this creature unless you pay {1}."

({T}: Add {G} or {U}.)

({T}: Add {W} or {U}.)

({T}: Add {U} or {B}.)

{1}: The next time an unblocked creature of your choice would deal combat damage to you this turn, prevent all but 1 of that damage.

As long as this creature is untapped, noncreature artifacts you control can't be enchanted, they have indestructible, and other players can't gain control of them. This effect doesn't remove Auras already attached to those artifacts.

{X}, {T}: Untap X target lands.

Red creatures get +1/+1. Whenever a Mountain is tapped for mana, its controller adds an additional {R}.

If this artifact would enter, you may discard a land card instead. If you do, put this artifact onto the battlefield. If you don't, put it into its owner's graveyard. {T}: Add one mana of any color.
