Drannith Ruins

Activated abilities of creatures you control cost 2 less to activate. This effect can't reduce the mana in that cost to less than one mana.

Each other Human you control gets +1/+0 and has ward 1. (Whenever it becomes the target of a spell or ability an opponent controls, counter it unless that player pays 1.)

As this enchantment enters, choose a planeswalker type. Planeswalkers you control of the chosen type have hexproof. As long as you control a creature, if damage dealt to a planeswalker you control of the chosen type would result in all loyalty counters on it being removed, instead all but one of those counters are removed.

Vigilance Whenever this creature deals combat damage to a player, return target artifact or enchantment card from your graveyard to the battlefield.

Flying, vigilance You have hexproof. Whenever this creature is dealt damage, you gain that much life.

When this enchantment enters, draw a card. Each planeswalker with one or more loyalty counters on it loses all abilities and is a creature with power and toughness each equal to the number of loyalty counters on it.

Each creature you control has "T: Add one mana of any of this creature's colors. Spend this mana only to activate an ability of a creature. Activate only if this creature has another activated ability." WUBRG, T: Mill five cards. Put all creature cards with activated abilities that aren't mana abilities from among the milled cards into your hand.

Return all noncreature, nonland permanents to their owners' hands.
