Land changer

Land changers are effects or spells that change a land card's land type. Changing lands (Target land becomes the basic land of your choice.) nowadays is primarily a blue ability. It allows blue a way to get access to other colors in multicolor environments.

Description
Note that the land type-changing effects are not the same as the subtype of text-changing effects.

Changing a permanent's land subtypes is special in two ways:
 * Unless the effect adds the type "in addition to its other types", not only does it lose all other land types, it also loses all abilities generated by its text and copy effects. For example, an animated Blinkmoth Nexus that "is a Forest" can't tap for, but it still has flying, because that ability was given to it by an effect. On the other hand, a Darksteel Citadel that "is an Island" no longer has indestructible.
 * Notwithstanding the above, any land with a basic land type has the mana ability appropriate for the type (unless an effect removes it). For example, if a Gruul Guildgate becomes a Forest, it has "undefined: Add ." (but it can't tap for, because it lost that ability).
