Concord — Whenever Chitinborn Sentry attacks, if there are four or more card types among permanents you control, prevent all damage that would be dealt to target attacking creature this turn.

Whenever you make first contact, you may draw a card. If you do, put a card from your hand on the bottom of your library. (You make first contact the first time each turn you cast a spell with a name not in your graveyard or control already.)

Look at the top two cards of your library. Put one of them into your hand and the other on the bottom of your library.

When Cai Lan enters, exile target nonland permanent an opponent controls with mana value 2 or less. Its controller creates an Idol token.

• Destroy target artifact or enchantment.

Look at the top eight cards of your library. You may reveal a creature card from among them and put it into your hand, then put the rest on the bottom of your library in a random order. Then if this spell was cast for its madness cost, you may put a creature card from your hand onto the battlefield.
