Flying
Whenever Hand of Genesis deals combat damage to a player, manifest the bottom card of your library. (To manifest a card, put it onto the battlefield face down as a 2/2 creature. Turn it face up any time for its mana cost if it's a creature card.)

Whenever you attack, you may pay {R}{W}. If you do, create a tapped and attacking token that's a copy of target attacking creature. Sacrifice the token at the beginning of the next end step.

Target creature and all creatures with the same name as that creature get +2/+1 and gain lifelink until end of turn.

{T}: Add {C}.
{T}, Sacrifice Fluctuating Locale: Rediscover a land card. (Look at the top card of your library. You may reveal it and put it into your hand if it's a land card. Otherwise, put it back or into your graveyard.)

Up to two target creatures each get +X/+X until end of turn. They must be blocked this turn if able.

Shroudmaker's Domain enters tapped.
{T}: Add {W}.

Vigilance
Whenever one or more creatures you control deals combat damage to a player, you may discard a card. If you do, create a Function token with “Draw two cards.” (It's an enchantment. As you cast an instant or sorcery spell, sacrifice any number of Functions to add their effects to that spell.)

Whenever another nonland permanent you control enters, return that permanent to its owner's hand at the beginning of the next end step.

Flash
When Thornweald Cavalier enters, target creature gets +1/+1 until end of turn. Put a reach counter on it.

This spell costs {1} less to cast for each storied permanent you control. (Enchantments and legendary permanents are storied.)

Choose target creature, then choose two —
• The chosen creature gets +3/+0 until end of turn.

{T}: Add {B} or {G}.

Whenever you detain a permanent, you gain life equal to that permanent's mana value.

[–1]: Tap target nonland permanent. It doesn't untap during its controller's next untap step.
[–2]: Put target nonland permanent into its owner's library second from the top.
[–X]: Shuffle up to X cards from your hand into your library, then draw that many cards. You gain that much life.

Search your library for a permanent card with mana value X or less, reveal it, put it into your hand, then shuffle.

Whenever you cast a noncreature spell, you may put a progress counter on Sovereign Skies.
[PROGRESS 2+] Indestructible
{T}: Add {C}.
[PROGRESS 9+] Sovereign Skies is a 9/9 Ship artifact creature with flying.

Enchant creature
{X}{B}: Enchanted creature gets +X/+X until end of turn.
When enchanted creature dies, return it to the battlefield under your control.

Put target creature on the bottom of its owner's library.
Each player conjures a card named Fatigue and puts it on top of their library. (It's a colorless sorcery that costs {2} with “Draw a card.”)

Flying, haste
When Crimson Hellmaw enters, it deals 3 damage to any target.
Revive {5}{R}{R} ({5}{R}{R}, Exile this card from your graveyard: Create a token that's a copy of it except it has no mana cost. Revive only as a sorcery.)

Haste

Gain control of target creature with power 2 or less until end of turn. Untap that creature. It gains haste until end of turn.
