There's a joke here about paying 6 mana just to get a 1/1 lifelinker in white because white bad. That being said, this is your finisher in Limited, especially if we get GW tokens and/or WU blink as draft archetypes.
Guarded Heir5W
Creature - Human Noble (Uncommon)
Lifelink (Damage dealt by this creature also causes you to gain that much life.)
When this creature enters, create two 3/3 white Knight creature tokens. The fate of the kingdom rests on her shoulders, and her subjects will not leave her side until she is old enough to rule.
1/1
Oh, and Stroke of Midnight is going to be Standard-legal for the next 5 years.
"Who was that skilled and graceful knight? Why did she leave before the food was gone?"
