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.)

Lifelink
Whenever Jerrold, Fugitive or another creature you control enters, if you cast it, you may cast target instant or sorcery card from your graveyard with lesser mana value by paying life equal to its mana value rather than paying its mana cost. Exile that card instead of putting it anywhere else as it resolves.

Choose one or more. You may choose the same mode more than once.

Flying

At the beginning of your upkeep, choose a creature. Its controller may sacrifice it. If that player doesn't, you gain life equal to its power.

[+2]: Create a 1/1 blue Bird creature token with flying.

({T}: Add {U}.)
Inundated Sanctuary enters tapped with two sanctum counters on it.

Archive 3 (As this enters, shuffle the top three cards of your main library into a new face up library. Sacrifice this after the archived library is empty.)
You may cast the top card of the archived library. Whenever you do, copy that spell. You may choose new targets for the copy.

Flying
When Sage of Storms enters, untap another target creature you control with flying and put a +1/+1 counter on it.

Landfall — Whenever a land you control enters, Convoy's Companion gets +1/+1 until end of turn. If that land was a Desert, put a +1/+1 counter on it instead.

Return target creature to its owner's hand. If you controlled that creature, draw a card.

Sacrifice a creature: Put a +1/+1 counter on Bloodlash Caravan. Then if it's the only creature you control, it gains indestructible until end of turn.

{3}{U}, Sacrifice Mystic Mackerel: Return target enchantment, instant, or sorcery card from your graveyard to your hand.
