Timeworn Sentinel

Endurance - Units with Endurance ready at the start of each players turn, so they can attack and still be ready to block during the enemy turn. Additionally, they are completely immune to enemy stun and exhaust effects.

Ally - Happens as soon as you have a unit of the named type. This can be when you play the unit with Ally or later if there's none of the needed type in play. Ally resets if the unit dies or is returned to hand.
