You may tap or untap target permanent.
Draw a card.

Enchant creature
Enchanted creature has lifelink and protection from its colors. This effect doesn't remove Shimmerhold. (This permanent can't be targeted, dealt damage, enchanted, or equipped by anything its color.)

Flying, haste
Whenever Shimmering Dragon attacks, for each creature you control, create a tapped and attacking token that's a copy of that creature. Exile the tokens at the beginning of the end step.

Whenever equipped creature attacks, put a charge counter on Shimmersting, then create a token that's a copy of equipped creature and that's tapped and attacking for each charge counter on Shimmersting, except the tokens aren't legendary. Exile the tokens at the beginning of the end step.
Equip {5}

Whenever you cast a noncreature spell, Shiverpass Taskmage explores. (Reveal the top card of your library. Put it into your hand if it's a land. Otherwise, put a +1/+1 counter on this creature, then you may mill that card.)

Equipped creature gets +2/+0.
Equipped creature has first strike as long as it's attacking.
Equip {2}

Vanguard — Whenever a creature you control attacks alone, Shocking Ewe deals 2 damage to defending player.

Whenever Shoreline Stormers deals damage to a player, draw a card.
{2}{U}: Target creature can't be blocked this turn.

Heretic (Whenever you cast a spell that doesn't share a color with this creature, it gets +1/+1 until end of turn.)
When Shoring Naiad enters the battlefield, if {U} was spent to cast it, you may return an instant or sorcery card from your graveyard to your hand.

Reveal the top four cards of your library. You may put a permanent card revealed this way with mana value less than the greatest mana value among permanents you control onto the battlefield. Put the rest on the bottom of your library in a random order.

Prevent all combat damage that would be dealt this turn. You get a glory counter. (You lose glory counters before life. A player with ten or more glory counters wins the game.)

Haste
Each creature with toughness greater than its power can't block.

Whenever equipped creature deals damage to a creature, that creature gets -2/-2 until end of turn.
Equip {2}

Extort (Whenever you cast a spell, you may pay {W/B}. If you do, each opponent loses 1 life and you gain that much life.)
Artifacts and creatures your opponents control enter the battlefield tapped.

Draw three cards, then discard a card unless you've catalyzed three or more times this turn.

Prowess
{T}: Catalyze, then catalyze again. Activate only if Sigil Slinger's power is 5 or greater. (The next spell you cast this turn costs {2} less to cast.)

Whenever target creature deals combat damage to a player this turn, create a token that's a copy of it.

Enchant creature
Enchanted creature gets +1/+1 and has hexproof.

As Silent Hypnotist enters the battlefield, choose a noncreature card name.
Spells with the chosen name can't be cast.
Activated abilities of sources with the chosen name can't be activated unless they're mana abilities.

As long as you are glorious, you may look at the top card of your library. (You are glorious as long as you have a glory counter.)

At the beginning of each end step, if you gained life this turn, you get a glory counter. (You lose glory counters before life. A player with ten or more glory counters wins the game.)

Death knell — You gain 2 life. (As a creature you control dies, trigger one death knell of that creature or another permanent you control.)

[+1]: Create a 1/1 blue Bird creature token with flying and haste.
[–1]: Creatures you control with flying get +1/+0 and gain vigilance until end of turn.
[–6]: Search your library for any number of creatures with flying and put them onto the battlefield. Shuffle your library.

Whenever you activate a nonmana ability of a permanent during your turn, you may choose one that hasn't been chosen yet this turn —
• That permanent becomes a 3/3 Dragon creature with flying in addition to its other types until end of turn.
• Each opponent discards a card and loses 2 life.
• Copy that ability. You may choose new targets for the copy.

Advance {3}{R} (Cast this for {3}{R} to advance it as it enters. {3}{R}: Advance this as a sorcery.)
Whenever another artifact creature enters the battlefield under your control or a permanent you control advances, Skalorian Orbguard deals 1 damage to any target.
