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.

Choose one —

Whenever you cast your third spell each turn, you may exile Devoted Artistry from your graveyard. If you do, you may cast a copy of it at the beginning of your next upkeep. (You still pay its costs.)

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.)

Haste
Whenever you cast a creature spell, it gains bloodthirst 1. (Multiple instances of bloodthirst on a spell stack.)

Whenever Devourer of Legacy deals combat damage to a player, you may sacrifice it and choose a nonland card name. If you do, search that player's graveyard, hand, and library for any number of cards with that name and exile them. That player shuffles, then draws a card for each card exiled from their hand this way.

If an effect you control other than a siphon ability would put a counter on a permanent, you may put a flying, vigilance, or stun counter on that permanent instead.

Flying
At the beginning of your upkeep, exile the top or bottom card of target player's library. That player loses life equal to that card's mana value.

As an additional cost to cast this spell, sacrifice a creature.
Search your library for up to X cards and put them into your hand, where X is the sacrificed creature's power, then shuffle.

You may cast spells as though they had flash.

Draw two cards. Then if this spell wasn't cast from your hand, create a Function token with “Compose.” (It's an enchantment. As you cast an instant or sorcery spell, sacrifice any number of Functions to add their effects to that spell.)

You can't lose the game.

Counter target spell.
If you countered a spell with mana value 2 or less this way, manifest dread. (Look at the top two cards of your library, then put one onto the battlefield face down as a 2/2 creature and the other into your graveyard. Turn it face up any time for its mana cost if it's a creature card.)
