mtg avatar the last airbender cards Booster Pack you may transform Aang MTG: Avatar: The Last Airbender

Mausoleum Wanderer is a blue Spirit creature with Flying that gets +1/+1 whenever another Spirit creature enters the battlefield under the owner's control

This alone would honestly be enough to account for the General Tazri MTG price spike

If the result of the roll is somehow less than 1 or greater than 20, the original spell or ability doesn't see heads nor tails (you'll have to read the effect carefully then to determine what happens)

When this land enters, return a land you control to its owner's hand
