Tranquil Frillback

At the beginning of your end step, if one or more creatures died this turn, you gain that much life and distribute that many +1/+1 counters among any number of creatures you control.

Each other Human you control gets +1/+0 and has ward 1. (Whenever it becomes the target of a spell or ability an opponent controls, counter it unless that player pays 1.)

Return up to one target artifact or enchantment card from your graveyard to the battlefield. Exile the top two cards of your library. Until the end of your next turn, you may play those cards.

Choose target land. Create three tokens that are copies of it, except they're 3/3 creatures in addition to their other types and they have vigilance and menace. (They're affected by summoning sickness.)

Whenever this creature enters or attacks, exile target card from a graveyard. Put a +1/+1 counter on this creature. This creature has flying as long as a card exiled with it has flying. The same is true for first strike, double strike, deathtouch, haste, hexproof, indestructible, lifelink, menace, reach, trample, and vigilance.

Return all noncreature, nonland permanents to their owners' hands.

Undergrowth — Distribute X +1/+1 counters among any number of target creatures you control, where X is the number of creature cards in your graveyard as you cast this spell. Creatures you control gain vigilance until end of turn.

Choose target permanent card in your graveyard. If it has mana value 3 or less, you may put it onto the battlefield. If you don't put it onto the battlefield, put it into your hand. You gain 3 life.
