Vishni, Lethrai Highblood

Flying - Flying units can only be blocked by other flying units, but can block ground units normally. They can also be directly attacked by Killer units and Relic Weapons.

Infiltrate - The special ability of a unit with Infiltrate occurs the first time that unit hits the enemy player. It doesn't work while the unit is on defense, such as when it is attacked by a Relic Weapon.

Steal - Taking an enemy card is stealing. Stealing a card removes its influence requirements.

Shift - When played, you may instead pay the Shift cost. Shifted units can't attack, block, or be selected until they emerge.

Emerge - After three turns, Shifted units emerge and get Unblockable that turn.
