Noble Purpose

Whenever a creature you control deals combat damage, you gain that much life.

At the beginning of your end step, for each player, put a +1/+1 counter on up to one target creature that player controls.
Each creature with one or more counters on it can't attack you or planeswalkers you control unless its controller pays {X}, where X is the number of counters on that creature.

Commander creatures you own have "Whenever this creature attacks, it gains double strike until end of turn."

Noble Banneret

As you draft a creature card, you may reveal it, note its name, then turn Noble Banneret face down.
