When Deputy Gibem enters, post a bounty on each creature and each planeswalker. (Put a bounty counter on those permanents. Each of them have “When this permanent dies, each opponent draws a card” as long as it has a bounty counter on it.)

Exile the top two cards of your library. Until end of turn, you may play cards exiled this way. If an instant or sorcery spell cast this way would deal damage to a player or planeswalker, it deals double that damage instead.

As an additional cost to cast this spell, you may sacrifice a creature.
Return to the battlefield a creature card in your graveyard that was put there from the battlefield this turn.

For each creature that's attacking you or a planeswalker you control, create a 1/1 blue Bird creature token with flying.

Archive 4 (As this enters, shuffle the top four cards of your main library into a new face up library. Sacrifice this after the archived library is empty.)

Trample
Creatures your opponents control get -1/-0.

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

Flash
When Devious Naiad enters, exchange control of it and target creature until end of turn. Untap that creature. It gains haste until end of turn.

Sacrifice Devoted Dancer: Target creature gains indestructible until end of turn. If it's your turn, shuffle Devoted Dancer into its owner's library.

Flying
At the beginning of your upkeep, for each seven cards in your graveyard, Devotee of Winds explores. (Reveal the top card of your library. Put that card into your hand if it's a land. Otherwise, put a +1/+1 counter on this creature, then put the card back or put it into your graveyard.)

Defender
Whenever another player casts an instant or sorcery spell, Devouring Spellroot gets +2/+2 until end of turn.
