Vigilance
Whenever Danuri Banisher deals combat damage to a player, you may exile target creature. If you do, return that card to the battlefield under its owner's control at the beginning of the next end step.

Vanishing 10 (This permanent enters with ten time counters on it. At the beginning of your upkeep, remove a time counter from it. When the last is removed, sacrifice it.)
If you would lose 1 or more life other than to pay a cost, instead remove that many time counters from Serene Prayer. (If you would lose more life than there are time counters on Serene Prayer, the life loss is still prevented.)

Spirited (When this creature enters, you may activate one of its activated abilities without paying its cost.)
{3}{G}, Sacrifice Jade Vault Reclaimer: Destroy target artifact or enchantment.

{4}, {T}: Look at the top card of your library. If it's a land card, you may put it onto the battlefield tapped. If you don't put the card onto the battlefield, put it into your hand.

Whenever Crain's Crony enters or attacks, reveal the top card of your library and put it into your hand. You lose life equal to that card's mana value.

Draw two cards. Add one mana of any color.

When Ravenous Chupacabra enters, destroy target creature an opponent controls.

Whenever Open Road or another permanent you control enters, if it has the greatest mana value among permanents you control, you may discard a card. If you do, draw a card.

{X}, {T}: Reveal the top card of your library. If its mana value is X or less, you may play it without paying its mana cost. Otherwise, put it into your hand. X can't be 0.
