Tel Vos Magister is summoned with a ward which will negate all damage taken from a single source. After taking damage, the ward will be broken and Tel Vos Magister will be susceptible to damage. Even with a ward, Tel Vos Magister can still be destroyed with instant kill cards such as Edict of Azura or Piercing Javalin.
If Tel Vos Magister still has a ward at the end of the player's turn, the player will gain a personal ward that will negate any damage directed at them before breaking. As such, the player can have a ward applied to them during all of their opponents turns so long as no attack is made against Tel Vos Magister. The ward will also prevent enemy creatures from draining or activating pilfer abilities.
If Tel Vos Magister's ward is broken, it can be regained with cards such as Wardcrafter or Elixir of Deflection. Friendly creatures with guard in the same lane as Tel Vos Magister will prevent his ward from being destroyed unless targeted by actions until the guard is destroyed or otherwise neutralized.
