Arcum's Weathervane

Put up to three target creature cards from your graveyard on top of your library.

At end of combat, if this creature attacked or blocked this combat, put a -0/-1 counter on this creature and create a 0/1 white Deserter creature token.

Enchant creature Enchanted creature gets +1/+2. 2U: Attach this Aura to target creature other than enchanted creature.

You may exile a white card from your hand rather than pay this spell's mana cost. Prevent the next 7 damage that would be dealt to any target this turn. If it's a creature, put a +0/+1 counter on it for each 1 damage prevented this way at the beginning of the next end step.

Destroy target artifact or enchantment.

2UU: Look at the top five cards of your library, put one of them into your hand, and exile the rest.

Shuffle a card from your hand into your library. If you do, draw two cards at the beginning of the next turn's upkeep.

T: Target creature gets +2/+2 until end of turn. When that creature leaves the battlefield this turn, sacrifice this creature. Activate only during combat.
