Flying, vigilance

Creature tokens you control have flying and vigilance.

Embalm {4}{W}{U} ({4}{W}{U}, Exile this card from your graveyard: Create a token that's a copy of it, except it's a white Zombie Bird Warrior with no mana cost. Embalm only as a sorcery.)

Counter target spell. If the spell is countered this way, exile it with three time counters on it instead of putting it into its owner's graveyard. If it doesn't have suspend, it gains suspend. (At the beginning of its owner's upkeep, remove a time counter from that card. When the last is removed, the player plays it without paying its mana cost. If it's a creature, it has haste.)

Flying

Whenever Derevi, Empyrial Tactician enters the battlefield or a creature you control deals combat damage to a player, you may tap or untap target permanent.

{1}{G}{W}{U}: Put Derevi onto the battlefield from the command zone.

Permanents you control gain hexproof and indestructible until end of turn.

Search your library for an enchantment card, reveal it, put it into your hand, then shuffle.

Whenever Mardu Shadowspear attacks, each opponent loses 1 life.

Dash {1}{B} (You may cast this spell for its dash cost. If you do, it gains haste, and it's returned from the battlefield to its owner's hand at the beginning of the next end step.)

Search your library for an instant or sorcery card, reveal it, then shuffle and put that card on top.

Destroy target artifact or enchantment. Its controller gains 4 life.

This spell costs {2} less to cast if an opponent controls a green permanent.

Deathtouch

Whenever Oakhame Adversary deals combat damage to a player, draw a card.

Whenever another creature enters the battlefield under your control, that creature gets +2/+0 and gains haste until end of turn. (It can attack and {T} this turn.)

{T}, Pay 1 life, Sacrifice Prismatic Vista: Search your library for a basic land card, put it onto the battlefield, then shuffle.

{0}: Remove target attacking creature you control from combat and untap it.

Whenever a creature you control attacks, it gets +1/+0 until end of turn for each other attacking creature that shares a creature type with it.

Put onto the battlefield under your control all creature cards in all graveyards that were put there from the battlefield this turn.

Exile target creature you don't control. For each creature exiled this way, its controller searches their library for a basic land card. Those players put those cards onto the battlefield tapped, then shuffle.

Overload {4}{W}{W} (You may cast this spell for its overload cost. If you do, change its text by replacing all instances of "target" with "each.")
