Lifelink
Sacrifice Devoted Apothecary: Remove a counter from target permanent.

Exile the top two cards of your library. Until your next end step, you may play those cards.
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.)

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

Vigilance (Attacking doesn't cause this creature to tap.)

Whenever a creature you control assaults, put a +1/+1 counter on Devoted Nomad.

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.)

Bloodthirst 1 (If an opponent was dealt damage this turn, this creature enters with a +1/+1 counter on it.)
Haste
Whenever you cast a creature spell, it gains bloodthirst 1. (Multiple instances of bloodthirst on a spell stack.)

Target creature you control deals damage equal to its power to another target creature. You gain life equal to the damage dealt this way.

Target player discards two cards.
Coalesce {8}{B} (You may cast this from your graveyard for {8}{B}. If you do, it enters as a Horror creature after it resolves. Exile it if it would leave the battlefield or not resolve.)

Flying, haste
{2}{B}: Devourer of Dread gets +1/+1 until end of turn. If there are three or more creature cards in your graveyard, put a +1/+1 counter on Devourer of Dread instead.

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.

Menace
Sacrifice a creature: Devouring Flame gets +2/+0 until end of turn.

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

Siphon (Each -1/-1 counter you put on your creatures up to their remaining toughness while casting this pays for {1}.)
Create an X/X green and blue Dryad creature token with ward {2}.

Flying, vigilance
{2}{G}: Return target creature you control to its owner's hand. If you do, this creature gets +2/+2 and gains trample until end of turn.

When Dewdrop Oracle enters, reveal the top four cards of your library. You may put a noncreature card from among them into your hand. Put the rest on the bottom of your library in any order.

Flying
When Dewdrop Ordainer dies, put a +1/+1 counter on target creature you control with a counter on it.

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.
