You may put a creature or land card from your hand onto the battlefield. Then each opponent may put a permanent card from their hand onto the battlefield. If one does, you may repeat this process.

Enchant player
Whenever one or more creatures attack enchanted player, their controller may sacrifice a creature. If they do, enchanted player loses 3 life, sacrifices a nonland permanent, and discards a card.

Haste
Whenever a player casts a spell, Rakkiri Dissident deals 1 damage to that player.

Choose target card in a graveyard other than a basic land card. Search its owner's graveyard, hand, and library for any number of cards with the same name as that card and exile them. Then that player shuffles.
Scry 1.

At the beginning of each player's upkeep, you may exile target permanent that player controls. If you do, return that card to the battlefield under its owner's control at the beginning of the next end step.

Experience (Whenever this creature attacks, if it has fewer than three +1/+1 counters on it, put a +1/+1 counter on it.)
When Worried Vulpine has three or more +1/+1 counters on it, remove them all and transform it.

When this permanent transforms into Worthy Vulpine or at the beginning of combat on your turn, creatures you control gain haste and trample until end of turn.
