Doctor Who

After an escaped permanent spell resolves, it enters the battlefield and will return to its owner's graveyard if it dies later.

Basic landcycling is a form of cycling. Any ability that triggers on a card being cycled also triggers on a card being basic landcycled. Any ability that stops a cycling ability from being activated also stops a basic landcycling ability from being activated.

Escape's permission doesn't change when you may cast the spell from your graveyard.

If a card has multiple abilities giving you permission to cast it, such as two escape abilities or an escape ability and a flashback ability, you choose which one to apply. The others have no effect.

If you cast a spell with its escape permission, you can't choose to apply any other alternative costs or to cast it without paying its mana cost. If it has any additional costs, you must pay those.

Once you begin casting a spell with escape, it immediately moves to the stack. Players can't take any other actions until you're done casting the spell.

To determine the total cost of a spell, start with the mana cost or alternative cost you're paying (such as an escape cost), add any cost increases, then apply any cost reductions. The mana value of the spell remains unchanged, no matter what the total cost to cast it was and no matter whether an alternative cost was paid.

Unlike the normal cycling ability, basic landcycling doesn't allow you to draw a card. Instead, it lets you search your library for a basic land card. You don't choose the type of basic land card you'll find until you're performing the search. After you choose a basic land card in your library, you reveal it, put it into your hand, then shuffle your library.
