Aven Courier

Alliance — Whenever another creature you control enters, create a Treasure token if this is the first or second time this ability has resolved this turn. Otherwise, you may pay X. When you do, this creature deals X damage to any target.

When this enchantment enters, for each player, put a contested counter on target land that player controls. Whenever a creature deals combat damage to a player, if that player controls one or more lands with contested counters on them, that creature's controller gains control of one of those lands of their choice and untaps it.

Choose three. You may choose the same mode more than once. • Until end of turn, target creature loses all abilities and has base power and toughness 1/1. • Target creature connives. (Draw a card, then discard a card. If you discarded a nonland card, put a +1/+1 counter on that creature.) • Target player returns a creature card from their graveyard to their hand.

Whenever a player attacks one or more of your opponents, that attacking player creates a Treasure token. If you would create one or more Treasure tokens, instead create those tokens plus an additional Treasure token. Sacrifice five Treasures: Put five +1/+1 counters on Jolene.

When this creature enters, put a shield counter on target noncommander creature you don't control. You gain control of that creature for as long as it has a shield counter on it. (If it would be dealt damage or destroyed, remove a shield counter from it instead.)

Choose three. You may choose the same mode more than once. • Create a token that's a copy of target creature you control. It gains haste. Sacrifice it at the beginning of the next end step. • Exile target artifact or enchantment. • Creatures target player controls get +1/+1 and gain first strike until end of turn.

Whenever this creature attacks, exile the top card of each player's library. You may play those cards this turn, and you may spend mana as though it were mana of any color to cast those spells. Blitz 2R (If you cast this spell for its blitz cost, it gains haste and "When this creature dies, draw a card." Sacrifice it at the beginning of the next end step.)

Casualty 2 (As you cast this spell, you may sacrifice a creature with power 2 or greater. When you do, copy this spell.) Each opponent exiles the top card of their library. You may cast spells from among those cards this turn. If you cast a spell this way, pay life equal to that spell's mana value rather than pay its mana cost.
