When Whisper Collector dies, draw a card.

Put target instant or sorcery card from your graveyard on top of your library.

Whenever a nontoken creature you control dies, you may pay {W} and exile Whispered Wishes from your graveyard. If you do, create a 1/1 white Spirit creature token with flying.

Whenever Whisperer of Fortunes attacks, the next card you foretell this turn costs {0} to foretell.
Whenever you cast a foretold spell, put a +1/+1 counter on Whisperer of Fortunes. It gains flying until end of turn.

Double strike

Target creature gains lifelink or winnow until end of turn. (Damage dealt to it also causes its controller to lose that much life.)

Improve {G} ({G}: Put a +1/+1 counter on this creature. This costs {1} more to activate for each +1/+1 counter on it. Improve only as a sorcery.)
If a +1/+1 counter would be put on a creature you control, you may put a deathtouch, reach, trample, or vigilance counter on it instead.

(Choose only one work as a sorcery to add its ability.)
When Wildlife Sketches enters the battlefield, reveal the top five cards of your library. Put a creature card from among them into your hand and the rest on the bottom in any order.
{1}{G}: Carnation Petals
You may cast creature spells as though they had flash.

{T}: Tap target creature. Activate only if Wizened Veteran is embattled. (A creature is embattled if it has a counter on it or a permanent you control attached to it.)
